How do you simplify #7+9times3-25 # using order of operations?

Answer 1

#29#

Occasionally referred to by the acronym PEMDAS (or a similar term), the sequence of operations is as follows:

Here it is:

#7color(brown)+9color(green)(xx)3color(brown)-5#

First, there is the multiplication:

#7+27-5#

and now, working from the left to the right:

#34-5#

Identify the number of terms first.

Terms are separated by #+ and -# signs.

Simplify each term first.

#color(blue)(7" ") color(green)(+" "9xx3" ") color(magenta)(-" "25)#

#=color(blue)(7" ") color(green)(+" "27" ") color(magenta)(-" "25)#

#=" "34" "-" "25#

#= 9#

To simplify (7 + 9 \times 3 - 25) using the order of operations, follow these steps:

Perform multiplication: (9 \times 3 = 27).
Perform addition and subtraction from left to right: (7 + 27 - 25).
Perform addition: (7 + 27 = 34).
Perform subtraction: (34 - 25 = 9).

Therefore, (7 + 9 \times 3 - 25 = 9).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
