Answer :
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.
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.
