ARITHMETICS 1A


Evaluate 16 x 237 + 463 x 16.

Solution

= 16 x 237 + 463 x 16

= 16 x (237 + 463)     factoring out the common number

= 16 x 700   

= 11200      [after multiplying 16 and 7 and adding two zeros on the answer]

Hence 16 x 237 + 463 x 16 = 11200

TRY THIS………….



Evaluate 121 x 516 + 484 x 121.
