Question

if ×means +, ÷means-,-means×and+means÷then 8×7-8+40÷2=?​

Answer 1

Answer:

Step-by-step explanation:

→ × = +

→ ÷ = -

→ - = ×

→ + = ÷

→ then 8 × 7 - 8 + 40  ÷ 2

→ changing the signs = 8 + 7 × 8 ÷ 40 - 2

→ 8 + 7 × (8/40 simplify ) - 2

→ 8 + 7 × 1/5 - 2

→ 8 + (7×1/5) - 2

→ 8 + 7/5 - 2

→ (8+7/5) - 2

→ (8*5/1*5 + 7*1/5*1) - 2

→ (40/5 + 7/5) - 2

→ 47/5 - 2

→ 47*1/5*1 - 2*5/1*5

→ 47/5 - 10/5

→ 37/5
