To simplify this expression, we need to use the Order of Operations (PEMDAS) which means we must perform any calculations in parentheses first, then any exponents, then any multiplication or division from left to right, and finally any addition or subtraction from left to right.
Using PEMDAS, we step-by-step simplify the given expression as follows:
30 - 4 × 7 + 52
= 30 - 28 + 52 (4 × 7 is 28)
= 2 + 52
= 54
Therefore, the simplified form of the expression is 54.
Simplify:
30 - 4 × 7 + 52
