Question

(20-15+100)÷(-5)+3(2-4-7)+(-4-8)-(-5+2+3) proceso

Answer 1

(20 - 15 + 100) ÷ ( - 5) + 3 (2 - 4 - 7) + ( - 4 - 8) - ( - 5 + 2 + 3)

105 ÷ ( - 5) + 3 *( - 9) - 12 - 0

- 21 - 27 - 12

- 60

Answer 2

20−15+100 / −5  +3(2−4−7)−4−8−(−5+2+3)

=5+100 / −5  +3(2−4−7)−4−8−(−5+2+3)

=105 / −5  +3(2−4−7)−4−8−(−5+2+3)

=−21+3(2−4−7)−4−8−(−5+2+3)

=−21+3(−2−7)−4−8−(−5+2+3)

=−21+(3)(−9)−4−8−(−5+2+3)

=−21+−27−4−8−(−5+2+3)

=−48−4−8−(−5+2+3)

=−48+−12−(−5+2+3)

=−60−(−5+2+3)

=−60−(−3+3)

=−60−0

=−60
