Question

⦁ Explain the difference between ""4 times the sum of x and y"" and ""the sum of 4 times x and y.""

Answer 1

In the first case, you perform the sum and then multiply by 4:

The sum of x and y ---> x+y

Four times the sum of x and y --->4(x+y)

In the second case, only x is multiplied by 4:

4 times x ----> 4x

The sum of 4 times x and y ---> 4x+y
