sometimes - a quadrilateral can be a rhombus but a quadrilateral can be other shapes as well.

4*3*2 + 6*3- 3(3 + 4) + 15

Lets use P.E.M.D.A.S

P = Parenthesis (Left to right)

4*3*2 + 6*3- 3*7 + 15

E = Exponents (We have none)

4*3*2 + 6*3- 3*7 + 15

M = Multiply (left to right)

24+18-21+15

D =  Divide (No Division)

24+18-21+15

Last, we Add and Subtract Left to Right (P.E.M.D.A.S)

= 36
