Question

Explain the difference between four times the sum of X and Y and the sum of four times X and Y

Answer 1

Condition 1:

four times the sum of X and Y = 4(X + Y)

Condition 2:

the sum of four times X and Y= 4X + Y

• Difference:

In condition 1, both the variables are first added and then multiplied by four. This can be simplified as:

4X +4Y

I condition 2, only the variable X is multiplied with 4 and then added to Y.

• Conclusion:

With positive integers, condition 1 will always give a greater value.

With negative integers, condition 2 will have greater value.
