Which expression represents "subtract 5 from 10 then multiply by 4"?
5−10 x 4 **
4 x (10−5)
4 x (5−10)
10−5 x 4
Is that correct?
(10-5)*4 because of the Order of Operations
The correct expression that represents "subtract 5 from 10 then multiply by 4" is 4 x (10−5).
To determine which expression represents "subtract 5 from 10 then multiply by 4," we need to follow the correct order of operations. The order of operations states that we should perform operations inside parentheses first, then perform multiplication or division from left to right, and finally perform addition or subtraction from left to right.
Examining the given expressions:
1. 5 - 10 x 4: This expression performs multiplication before subtraction, so it does not represent the desired operation.
2. 4 x (10 - 5): This expression correctly represents the order of operations. It subtracts 5 from 10 and then multiplies the result by 4.
3. 4 x (5 - 10): This expression performs the subtraction in reverse order, so it does not represent the desired operation.
4. 10 - 5 x 4: This expression performs multiplication before subtraction, so it does not represent the desired operation.
Therefore, the correct expression that represents "subtract 5 from 10 then multiply by 4" is 4 x (10 - 5).
