To increase a number by another number.

To increase a number by another number.

• A. Add
• B. Subtract
• C. Divide
• D. Multiply

Answer: (D)

Increasing by a number means you are performing addition. When you say you increase one value by another, you’re combining the original amount with the extra amount to get a larger total. For example, increasing 7 by 4 gives 11, because you’re adding 4 to 7. The idea here is to add the second number to the first to make it bigger. Subtracting would take away, division would split into parts, and while multiplication can represent repeated addition, the straightforward meaning of “increase by” is addition.
