How do you evaluate #15-13+2#?

Answer 1

See below.

P.E.M.D.A.S.

Parenthesis Exponents Division Addition Subtraction Multiplication

Addition comes before subtraction so we need to add #13# and #2#
#13# #+# #2# #=# #15#

The updated formula is:

#15# #-# #15#

The only thing left to do is subtract, so

#15# #-# #15# #=# #0#
Our final answer is #0#

I hope I was of assistance.

PEMDAS is what we use.

#color(brown)(A)# and #color(brown)(S)# have the same weight and so we work from left to right:
#15-13+2#
#=2+2#
#=4#

Answer 3

To evaluate ( 15 - 13 + 2 ), you perform the subtraction and addition operations according to the order of operations (PEMDAS/BODMAS). ( 15 - 13 = 2 ) Then, ( 2 + 2 = 4 ). So, the result of ( 15 - 13 + 2 ) is ( 4 ).

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.
