Question

Evaluate ab - cd =
a = 5, b = 3, c = 4, d = 2

Answer 1

7

Explanation:

ab - cd = ?

Put the numbers into the correct variables of the equation.

(5)(3) - (4)(2) = ?

Now multiply 5 and 3 with each other. This leaves you with:

15 - (4)(2) = ?

Now, multiply 4 and 2 with each other. This leaves you with:

15 - 8 = ?

Now, you are able to solve the equation.

15 - 8 = 7
