B) Divide by -1
C) Add the opposite
D) Subtract the opposite

Answer 1

To make a problem true by adding or getting rid of a negative sign, you can multiply by -1 or add the opposite of the number.

Step-by-step explanation:

1. To make a problem true by adding or getting rid of a negative sign, you can:
   • Multiply by -1: Multiplying a number by -1 changes the sign of the number. For example, -3 multiplied by -1 becomes 3.
   • Add the opposite: Adding the opposite of a number is the same as subtracting the number. For example, 5 plus the opposite of 4 equals 5 - 4 = 1.
2. Divide by -1 and subtracting the opposite are not valid methods for changing the sign of a number.
