Exam 1: Some Basic Concepts of Arithmetic and Algebra

Simplify the algebraic expression below, and then evaluate the resulting expression for the given values of the variables. 26( m $-$ 6) $-$ 13( m + 20) for m = 9

Find the quotient. $\frac { - 48 } { 4 }$

Simplify the numerical expression below. (28)( $-$ 11)( $-$ 2)
