DiKsa [7]

Answer: The different possible solutions are 42, 21, 31 and 80.

Explanation:

The given expression is,

7+3\cdot 4+2

Case 1.

(7+3)\cdot 4+2=10\cdot 4+2

(7+3)\cdot 4+2=40+2

(7+3)\cdot 4+2=42

Case 2.

7+(3\cdot 4)+2=7+12+2

7+(3\cdot 4)+2=21

Case 3.

7+3\cdot (4+2)=7+3\cdot 8

7+3\cdot (4+2)=7+24

7+3\cdot (4+2)=31

Case 4.

(7+3)\cdot (4+2)=10\cdot 8

(7+3)\cdot (4+2)=80
