calculate with integer
1.) calculate
a.) $-52 + 16$
b.) $-102 - 206$
c.) $250 - (-30) + (-20)$
2.) a.) what is 258 plus 329?
b.) what is 258 plus -329?

Explanation:

Step1: Compute negative + positive

$-52 + 16 = -(52 - 16) = -36$

Step2: Compute negative - positive

$-102 - 206 = -(102 + 206) = -308$

Step3: Simplify signs then calculate

$250 - (-30) + (-20) = 250 + 30 - 20 = 260$

Step4: Add two positive integers

$258 + 329 = 587$

Step5: Add positive + negative

$258 + (-329) = 258 - 329 = -(329 - 258) = -71$

Answer:

1.) a) $-36$
1.) b) $-308$
1.) c) $260$
2.) a) $587$
2.) b) $-71$
