How do you simplify #7 - 25 + 3 times 25# using order of operations?

Answer 1

Nathan Axel

#57#

#7 - 25 + 3 xx 25#

A good way to remember the order of operations is PEMDAS, shown here:

Following this image and what we need to simplify, we first need to do multiplication:
#7 - 25 + 75#

Since addition and subtract are equal in the order of operations, do it from left to right:
#-18 + 75#

#=57#

Hope this helps!

To simplify the expression using the order of operations:

First, perform the multiplication: (3 \times 25 = 75).
Then, perform the addition and subtraction from left to right: (7 - 25 + 75 = -18 + 75 = 57).

So, the simplified expression is (57).
