How do you evaluate #15 - 2 +12 \times 2#?

Answer 1

See below

Use order of operations PEMDAS In this case, we multiply first #15-2+24# Now subtract #15-2# #13+24# #37# =

Answer 2

#37#

When doing calculations which involved different operations, identify the individual TERMS first. Terms are separated by #+ and -# signs,

Within each term, do:

Simplify each term to a single answer and then add or subtract them in the last step.

#color(red)(15)" "color(blue)(-2)" "color(forestgreen)( +12xx2)" "larr# there are 3 terms
#=color(red)(15)" "color(blue)(-2)" "color(forestgreen)( +24)#

It is a good idea to write the adds at the beginning and the subtracts at the end.

(In this case is does not matter, but this helps to avoid errors in other examples)

#= color(red)(15)" "color(forestgreen)( +24)" "color(blue)(-2)#
#= 37#

Answer 3

To evaluate (15 - 2 + 12 \times 2), follow the order of operations, also known as PEMDAS:

  1. Perform multiplication first: (12 \times 2 = 24).
  2. Then, perform addition and subtraction from left to right: (15 - 2 + 24).
  3. Now, perform addition and subtraction: (15 - 2 = 13).
  4. Finally, add the result to the previous multiplication: (13 + 24 = 37).

So, (15 - 2 + 12 \times 2 = 37).

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.
