The key on the calculator used to change the sign of a number is called:
A) Plus/minus key
B) Negative number key
C) Reverse key
D) Subtract key

Question

Quizplus · Accepted Answer

The plus/minus key is typically represented by a symbol that looks like ± or -/+ and allows users to switch the sign of a number from positive to negative or vice versa. It is not the subtract key (D) as that key is used for subtraction operations, not sign changes. The negative number key (B) and reverse key (C) are not commonly used terms in calculator terminology.
