What’s the answer for 7+25•4

kotykmax [81]

Use Order of Operations!! Remember PEMDAS!
P: Parentheses first
E: Exponents (ie Powers and Square Roots, etc.)
MD: Multiplication and Division (left-to-right)
AS: Addition and Subtraction (left-to-right)

7+25•4 (multiply 25 by 4 first)
7+100 (then add 7 to 100)
107

So your final answer would be 107

Hope this helped and I hope you have an awesome day!! :D
