Question
Select the correct combination of mathematical signs
from the options given to replace # signs and get a balanced equation. 24 #8 #4 # 10 # 2Solution
1) 24 # 8 # 4 # 10 # 2 24 – 8 ÷ 4 + 10 = 2 24 – 2 + 10 = 2 20 + 10 = 2 32 ≠ 2 2) 24 # 8 # 4 # 10 # 2 24 + 8 = 4 + 10 – 2 32 = 14 – 2 32 ≠ 12 3) 24 # 8 # 4 # 10 # 2 24 = 8 x 4 – 10 + 2 24 = 32 – 10 + 2 24 = 22 + 2 24 = 24 4) 24 # 8 # 4 # 10 # 2 24 + 8 x 4 = 10 + 2 24 + 32 = 12 56 ≠ 12
