Question
Select the correct combination of mathematical signs
that can sequentially replace the sign * and make the equation correct. 3 * 12 * 4 * 5 * 4 * 116Solution
1) 3 * 12 * 4 * 5 * 4 * 116 3 x 12 + 4 x 5 x 4 = 116 36 + 80 = 116 116 = 116 2) 3 * 12 * 4 * 5 * 4 * 116 3 x 12 ÷ 4 + 5 ÷ 4 = 116 3 x 3 + 1.25 = 116 9 + 1.25 = 116 10.25 ≠ 116 3) 3 * 12 * 4 * 5 * 4 * 116 3 x 12 – 4 + 5 ÷ 4 = 116 3 x 12 – 4 + 1.25 = 116 36 – 4 + 1.25 = 116 33.25 ≠ 116 4) 3 * 12 * 4 * 5 * 4 * 116 3 x 12 – 4 – 5 = 4 + 116 36 – 4 – 5 = 116 27 ≠ 116
