Q. Evaluate

a+(-b)

where

a=4

and

b=2

.

Given Values: We are given: $\newline$ $a = 4$ $\newline$ $b = 2$ $\newline$ The expression to evaluate is $a + (-b)$ . $\newline$ Substitute $4$ for $a$ and $2$ for $b$ in the expression $a + (-b)$ . $\newline$ $a + (-b) = 4 + (-2)$
Substitute Values: Now, simplify the expression $4 + (-2)$ . $\newline$ Adding a negative number is the same as subtracting the number. $\newline$ $4 + (-2) = 4 - 2$
Simplify Expression: Subtract $2$ from $4$ . $\newline$ $4 - 2 = 2$
