Question

0.46 + (-0.642)

Please help!! Thank you!!

Answer 1

-0.182

Explanation:

Given expression:

• 0.46 + (-0.642)

It should be noted that;

1. Positive integer + (Negative integer) = Positive integer - Positive integer

• a + (-b) = a - b

2. Positive integer - (Negative integer) = Positive integer + Positive integer

• a - (-b) = a + b

Our case is point 1. Therefore,

• ⇒ 0.46 + (-0.642)
• ⇒ 0.46 - 0.642
• ⇒ -0.182
