SOLUTION

TO SOLVE

Using properties

 \sf{24 \times (42) + ( - 42) \times (32)}

CONCEPT TO BE IMPLEMENTED

Distributive PROPERTY

For there real numbers a , b , c

 \sf{a \times (b + c) = (a \times b) + (a \times c)}

EVALUATION

Here the given expression is

 \sf{24 \times (42) + ( - 42) \times (32)}

We simplify it as below

 \sf{24 \times (42) + ( - 42) \times (32)}

 \sf{ =( 24 \times 42)  - ( 42\times 32)}

Using commutative property we get

 \sf{ =( 24 \times 42)  - ( 32 \times 42)}

Using Distributive Property we get

 \sf{ =( 24  - 32) \times 42}

 \sf{ =(  - 8) \times 42}

 \sf{ = - 336}
