Answer:
The order of operations (PEMDAS) should be followed to solve mathematical expressions: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
So the solution for (7+3) x 4 ÷ 2 - 5 x 6
= (10) x 4 ÷ 2 - 5 x 6
= 40 ÷ 2 - 5 x 6
= 20 - 5 x 6
= 20 - 30
= -10
So the solution is -10
