You can add calculation results to or subtract results from independent memory.

The "M" indicator appears on the display when there is any value other than zero stored in independent memory.

Example 1:

To clear the contents of M
fx-82MS/fx-85MS/fx-300MS/fx-350MS:

• 0(STO)(M)
• 0.

fx-220 PLUS:

• 0(Min)
• 0.

To add the result of 10 × 5 to M

• (Continuing)　105
• 50.

To subtract the result of 10 + 5 from M

• (Continuing)　105(M-)
• 15.

To recall the contents of M
fx-82MS/fx-85MS/fx-300MS/fx-350MS:

• (Continuing)　(M)
• 35.

fx-220 PLUS:

• (Continuing)　
• 35.

Example 2:

23 + 9 = 32
53 - 6 = 47
-) 45 × 2 = 90
99 ÷ 3 = 33
(Total)　 22
