Evaluate the expression;

7 ⋅ 4 + 6 - 12 ÷ 4

I got 31. Here's my Equation.

7*4+6-12/4
28+6-3
34-3= 31

Use PEMDAS

Here, 7 . 4 + 6 - 12 ÷ 4
Do all the divisions first, 
7 . 4 + 6 - 3

Now, all the multiplications, 
28 + 6 - 3
Now, all subtraction, 
28 + 3
In last, do addition, 
31

In short, Your Answer would be 31

Hope this helps!
