Remember PEMDAS?
Parentheses
Exponents
Multiplication
Division
Addition
Substraction
Ok, so you have division, subtraction, and multiplication.
So you do them in this order:
1. Division
2. Multiplication
3. Subtraction
Division and multiplication are actually on the same level, but since you do the equation left to right, division comes first.
So...
1. 30/3=10
2. 4 x 2=8
3. 10 - 8=2
Therefore, your answer is 2.

1.Divide 30/3 which equals 10
2.Multiply 4X2 which equals 8
3. 10 - 8 = 2
on the other hand if 4*2 means 4 squared then its
4 squared first which equals 16 then 30/3 = 10 so
10-16 = -6

use PEMDAS (Please Excuse My Dear Aunt Sally)
Power, Exponent, Multiplication and Division (they go in order from left to right, whichever comes first), Addition and Subtraction (whichever comes first from left to right)
30/3-4*2
30/3 - 8
10 - 8
2

its PEMDAS(order of operations)
4x2=8
so then it becomees 30/3-8
30/3=10
10-8=2
WELCOME!
