how does 6 and 3 and 2 and 15 = 7

Question

PEDMAS

Answer 1

Order of Operations:

To simplify the expression follow the order of operations: (PEMDAS)

1.      Evaluate the expressions inside the Parenthesis/Brackets (P).

2.      Evaluate Powers/Exponents (E).

3.      Multiply and/or Divide in order from left to right (MD).

4.      Add and/or Subtract in order from left to right (AS).

From PEMDAS rule,

6 and 3 and 2 and 15 can be written as (6 * 2) - (15/3)

Evaluate the expression inside the Parenthesis

12 - 5                                       (Multiply : 6×2 =12 ;Devide : 15/3 = 5)

= 7.                                          (Subtrct :12 - 5 = 7)

So, the expression is (6 * 2) - (15/3).
