Question

insert the parentheses in expresion 2 so that it has value of 19 then show why your expression has value of 19

Answer 1

(a) What is the value of Expression 1?

Expression 1: 6 * 7 - 3^2 * 9 + 4^3

6 * 7 - 3^2 * 9 + 4^3

= 42 - 81 + 64

= 25

(b) Insert parentheses in Expression 2 so that it has a value of 19. Then show why your expression has a value of 19.

Expression 2: 5 + 4 * 2 + 6 - 2 * 2 -1

(5 + 4) * 2 + 6 - (2 * 2) -1

= 9*2 + 6 - 4 - 1

= 18 + 6 - 5

= 24 -5

= 19
