1.) You can distribute the 15 and get 1350-45=1305
2.) You can do 90-3 first. Then multiply 87 times 15 and get 1305.

Two ways to evaluate the expression 15(90-3) both yield the same result, 1305 and both ways are as follows;

Method 1:

  • 15 (90 - 3)

  • = 15 (87)

  • = 15× 87

= 1305.

Method 2:

  • 15 (90 - 3)

  • = (15×90) - (15×3)

  • = 1350 - 45

= 1305.
