    The full form of these keys itself says it all..

    MC = Memory Clear sets the memory to 0

    MR = Memory Recall uses the number in memory, acts as if you had keyed in that number yourself

    MS = Memory Store puts the number on the display into the memory

    M+ = Memory Add takes the number on the display, adds it to the memory, and puts the result into memory

    The buttons can be handy for doing repeated calculations with a single number. For instance, if you wanted to multiply a bunch of numbers by pi, you could key in the following:

    3.14159.. MS (stores the number)

    4 x MR = (gives you 4 times pi)

    25 x 25 x MR = (gives you 25×25 times pi)

    The M+ button can be handy for figuring out complicated expressions if you don’t happen to have a scientific calculator. For example, to calculate (5 x 6) + (12 x 2) + (3 x 7), you can do the following:

    5 x 6 = (calculator says 30)

    MS (stores 30 in memory)

    12 x 2 = (calculator says 24)

    M+ (takes 24, adds it to 30, stores result 54 in memory)

    3 x 7 = (21)

    M+ (takes 54, adds 21, stores the result 75)

    MR (displays the result 75)

    I think it will help you.

    Most calculators have the ability to store a number in memory in addition to the number that appears directly on the screen. The ms (memory store) button copies the number from the screen to the memory. The mr (memory recall) button brings the memory value back to the screen. M+ and m- add or subtract the screen value from the memory value (hiding the result in the memory, so you need to be careful not to double-press the button). Mc (memory clear) resets the memory value to zero. The mc and ms functions are functionally redundant, so some calculators will only provide one of them.

    These buttons work with the calculator’s memory, which stores one number:

    MC = Memory Clear sets the memory to 0

    MR = Memory Recall uses the number in memory, acts as if you had keyed in that number yourself

    MS = Memory Store puts the number on the display into the memory

    M+ = Memory Add takes the number on the display, adds it to the memory, and puts the result into memory

    The buttons can be handy for doing repeated calculations with a single number. For instance, if you wanted to multiply a bunch of numbers by pi, you could key in the following:

    3.14159.. MS (stores the number)

    4 x MR = (gives you 4 times pi)

    25 x 25 x MR = (gives you 25×25 times pi)

    The M+ button can be handy for figuring out complicated expressions if you don’t happen to have a scientific calculator. For example, to calculate (5 x 6) + (12 x 2) + (3 x 7), you can do the following:

    5 x 6 = (calculator says 30)

    MS (stores 30 in memory)

    12 x 2 = (calculator says 24)

    M+ (takes 24, adds it to 30, stores result 54 in memory)

    3 x 7 = (21)

    M+ (takes 54, adds 21, stores the result 75)

    MR (displays the result 75)

    Your calculator has a memory where it can store a number for later use.

    The MC key will Clear the Memory or make it store 0.

    The MR key will Recall the number in Memory to the display.

    The M+ or M- keys will add or subtract the number in the display to or from the current number in the memory.

    The MS key will Store the current display mumber in the memory, replacing what was already there.

    The 4 Worst Blood Pressure Drugs.

    Why some doctors in the know no longer prescribe blood pressure drugs.

    Whenever a number is to be repeated several times ,one need not press buttons of that number.every time

    The number is to be stored M S : Memory Store

    When the number is to be recalled press M R

    M R : Memory Recall

    After the mathematical operation is over clear the number M C : Memory Clear

    Shorts Answer: MU stands for ‘Mark Up’.

    Usage: [100] then [MU button] then [20] then [% button]. The answer will be [125].

    Example: Suppose a shopkeeper wants to sell the product at 100 after 20% discount. Then he can use mark up button. He will input [100] MU [20] % and the answer he gets is [125] that is the selling price he will have to write on the product.

    Explanation: The profit rate is relative to the selling price, meaning the percentage of the selling price that is profit.

    In the example above, the selling price (as computed by the calculator) is 125. Before performing the calculation, we did not know what the selling price would be, just that the purchase price of 100 and discount we want to offer i.e. 20%.

    After giving 20% discount shopkeeper have to sell a product at 100 so selling price on product should be 125.

    Validation: [125] the [-] then [20] then [% button]. The answer will be [100].

    Used by: Retail managers use it for marking up prices on goods.

    Fact: MU button is not related to memory.

    Calculator: Citizen Calculator provides this function appropriately.

    These are memory functions. Old or simple calculators have a memory register – essentially a second calculator that can handle addition/subtraction only.

    M+, M-: Add (or subtract) the current value to (or from) the stored value in the memory register.

    MR : Recall the current memory register value.

    MC : Clear the memory register (set to zero).

    This function could be useful when, for example, you are doing a bunch of individual calculations and want to keep a running total of the sum of the results. Say you are buying several items at different discounts.

    First make sure the memory is empty: MC (Memory = 0)

    Item 1 is $100 at a 10% discount: 100*.9 = 90 M+ (Memory = 90)

    Item 2 is $200 at a 30% discount: 200*.7 = 140
    M+ (Memory = 230)

    Item 3 is $150 at a 20% discount: 150*.8 = 120
    M+ (Memory = 350)

    How much did I spend altogether? MR. 350!

    CE = Clear Entry. It clears only the current entry.

    CC = Clear Content. Clears everything (except independent memory M+).

    AC = All Clear. Same as CC.

    C = Some calculators write C instead of CC.

    M- = Clears value stored in independent memory (M+).

    If you are doing a calculation 1+2+3+4+5, and you’ve typed 1+2+3+4, now if you press CE, only last entered value 4 will be deleted, 1+2+3 (=6) will be in memory, you can enter +7= you’ll get 13.

    But if you press CC at that point instead of CE, everything will be cleared, calculator will show 0 only.

    I hope I was able to clear the difference. You can watch my videos below.

    The game deserves praise for its impressive graphics and visuals, plus a great soundtrack.

    MU means ‘mark up’.

    Say figure X has been reduced by 20% to 100 and you want to discover the value of X (for example, you are paid £100 net after 20% tax has been deducted and you want to know your gross earnings).

    On a Casio calculator enter: [100] then [MU button] then [20] then [% button]. The answer ‘125’ is displayed. (Therefore you earned £125 before tax).
