Question

Assume a * b means a + b - 1. What is 5 * 3 ?​

Answer 1

The result of 5 * 3 using your operation would be 7.

Answer 2

7

Explanation:

Since a*b = a + b - 1 , we can practically just substitute these new values into this equation.

a*b will represent 5*3:

5*3= a + b - 1

a=5

b=3

5*3 = 5 + 3 - 1

This is just equal to 7. Hope this helps!
