Answer
31
Work Step by Step
To evaluate
4+5x6-3
use PEMDAS (Parentheses or grouping symbols, Exponents, Multiplication and Division in the order they appear, Add and Subtract in the order they appear).
There are no grouping symbols or exponents, so I start with multiplication and division. There is one multiplication sign so I start there.
5x6= 30
so 4+5x6-3 = 4+30-3.
There is no more multiplication or division so I do the addition and subtraction in the order they appear.
4+30=34
Now I have 34-3
34-3=31.
