Question from Raina, a parent: I have four numbers 3 3 9 5 that need to equal 24 using addition subtraction multipliction and division and I'm so stuck. |
We have three responses for you
Hi Raina,
Think of two numbers that multiplied together equal 24, then try to form those two numbers from the numbers given to you.
hint: to form the two numbers to multiyply you will add two of the given numbers together, and use subtraction on the other two.

Raina,
How about 39 - 3x5 ?
