Given:
Sign
÷
+
×
-
Means
+
-
÷
×
Evaluate each option:
Option A: 36 × 4 + 3 – 6 ÷ 16 = 7
New Equation:
36 ÷ 4 − 3 × 6 + 16 = 7
= 9 − 3 × 6 + 16
= 9 - 18 + 16
= 25 - 18
= 7 = 7 (Follow)
Option B: 36 + 4 ÷ 3 × 6 – 16 = 40
New Equation:
36 − 4 + 3 ÷ 6 × 16 = 40
= 36 − 4 + 0.5 × 16 
= 36−4 + 8 
= 32 + 8
= 40 = 40 (Follow)
Option C: 36 – 4 × 3 + 6 ÷ 16 = 60
New Equation:
36 × 4 ÷ 3 − 6 + 16 = 60
= 36 × 1.333 − 6 + 16
= 48 + 16 - 6
= 64 - 6
= 58 \not= 60 (Not Follow)
Option D: 36 ÷ 4 – 3 × 6 + 16 = 22
New Equation:
36 + 4 × 3 ÷ 6 − 16 = 22
= 36 + 4 × 0.5 − 16
= 36 + 2−16
= 38 - 16
= 22 = 22 (Follow)
So, the option C is not correct .
Thus, the correct option is: (c)
