Question

Using suitable properties, 458*(-99)+(-458)​

Answer 1

$458 \times(-99) + (-458)\\\\= 458 \times (1-100) - 458\\\\= 458 - (458 \times 100) - 458\\\\= -(458 \times 100)\\\\=-45800$

Answer 2

458*(-99)+(-458)

= 458(-100+1) - 458

= 458(-100) + 458(1) - 458 ( Distributive property)

= - 45800 +458-458

= - 45800 + 0

= -45800
