      These familiar buttons add, subtract, multiply, and divide the number you’ve entered.

    • mc, m+, m-, mr: These are memory functions. You can, in order, clear memory, add a calculation into memory, deduct a calculation from memory, or retrieve the memory results.

    • +/–: If the calculator is displaying a negative result, tap this to change it to a positive result, and vice versa.

    • AC/C: This is the clear button; its name will change depending on whether you’ve entered one item or several (AC clears all; C clears just the last entry).
