For this case we must find the value of the following expression:
[tex]-112.84-54.14 - (- 29.18) =[/tex]
The law of the signs of multiplication states that:
[tex]- * - = +\\-112.84-54.14 + 29.18 =[/tex]
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.
[tex]-166.98 + 29.18 = -137.8[/tex]
Answer:
-137.8
