To simplify, apply the order of operations known as PEMDAS (Parenthesis, Exponent, Multiplication/Division, and Addition/Subtraction.
Note that the operations involved in the given expression are subtraction, addition and multiplication.
So multiply first 5 and 0, since in PEMDAS, multiplication comes before addition and subtraction.
Then, moving from left to right in the resulting expression, do the subtraction.
And, do the addition.
Hence, `9-5+5*0+3=7` .
