What is the value of –112.84 – 54.14 – (–29.18)?

Answer 1

For this case we must find the value of the following expression:

$-112.84-54.14 - (- 29.18) =$

The law of the signs of multiplication states that:

$- * - = +\\-112.84-54.14 + 29.18 =$

We add similar terms, taking into account that equal signs are added and the same sign is placed, while different signs are subtracted and the sign of the major is placed.

$-166.98 + 29.18 = -137.8$

Answer:

-137.8
