To store use the STO button. You can store a number in the memory registers A, B,C,D, and maybe E and F if you have the last two. Also in X, Y, and M.
Example: To store 15 in A
15 STO A[=/EXE]
To recall from a memory location use the RCL button
RCL A displays 15
For simple scientific calculators, you have a certain number of memory locations A, B, C, D, X,Y, M. Maybe more,
To store a value in a memory location you use the [STO] or
[SHIFT] [RCL] (STO) sequence.
15 [STO] A (displays 15)
[RCL] A (displays 15)
For graphing calculator, you have 26 memory locations, one in each letter. You use the STO key to store as above. You may also have the possibility to store programs, and on certain models a text editor.
I do not know what make and model of calculator you have, but generally speaking, the M key stands for Memory key, When you press it it brings the content of the memory register on the display. But if you have not stored anything in memory (by entering a number then pressing M+) then the calculator displays the default value in memory, which is 0.
You can store values in the memory locations the calculator has (A,B,C, D, M). However they will may not remain stored once the calculator is turned off. To store a value in say Memory location A type in the number and press STO> A. If that does not work, type in a number and press STO> ALPHA A To retrieve a stored value, press RCL A or RCL ALPHA A
Hello, Your calculator has 3 memories (M1, M2,M3) To store the number 170 in M1 use 170[STO]1 To recall a number from M1 use [RCL]1 To add a number to the content of M1 [2nd][SUM]1 (adds displayed value to contents of M1). [2nd][EXC] 2 exchanges the value already displayed with the contents of M2:
To erase (clear) a memory register, just store 0 in it.
