Question

Simplify

$146-(-200)-(-90)$

Answer 1

Subtraction is opposite of addition. So, to subtract an integer a from another integer b we add the additive inverse of a to b.

Taking out the additive inverse of second integer given,

Additive inverse of $-200$ is $200$

Taking out the additive inverse of second integer given,

Additive inverse of $-90$ is $90$

$146-(-200)-(-90)=146+200+90$$=436$

Hence, the final answer is $436$
