Q. Evaluate the expression for

m = -2

and

n = -0.6

.

\newline

Write your answer as a decimal or whole number.

\newline

mn - n =

_____

Identify Expression: Identify the expression to be evaluated. $\newline$ The given expression is $mn - n$ . We need to substitute $m = -2$ and $n = -0.6$ into this expression.
Substitute Values: Substitute the values of $m$ and $n$ into the expression. $\newline$ Substitute $m = -2$ and $n = -0.6$ into the expression to get $(-2)(-0.6) - (-0.6)$ .
Perform Multiplication: Perform the multiplication. $\newline$ Multiply $-2$ by $-0.6$ to get $1.2$ .
Perform Subtraction: Perform the subtraction. $\newline$ Subtract $-0.6$ from $1.2$ to get $1.2 - (-0.6) = 1.2 + 0.6$ .
Simplify Addition: Simplify the addition. $\newline$ Add $1.2$ and $0.6$ to get $1.8$ .
