Given:
50 - 20 + 5 x 25 - 4
Determine which operation must be performed first to simplify the expression.
Solution:
In order to simplify the expression, since we are given multiples values and operation, we apply the rules of PEMDAS. PEMDAS, means you must first start with the parenthesis, exponent, multiplication, division, addition, and lastly subtraction.
Based on the given condition of PEMDAS, we start first with the operation of multiplication, since we do not have an exponent or parenthesis.
= 50 - 20 + 5 x 25 - 4
= 50 - 20 + 125 - 4
= 50 + 105 - 4
= 155 - 4
= 151
Final answer:
= 151
