A8

B9

C4

D10

Answer:

B. 9

Read Explanation:

Given the substitutions:

  • + means ÷

  • - means ×

  • × means +

Replace the operators in:

12+4×2−312 + 4 \times 2 - 3

to get:

12÷4+2×312 \div 4 + 2 \times 3

Now apply the standard order of operations (÷ and × before +):

12÷4=312 \div 4 = 3
2×3=62 \times 3 = 6
3+6=93 + 6 = 9

Answer: 9
