well, first you change the + to a minus and you make the negative a positive, so its 14b-21b+37b. then you do simple addition/subtraction. your answer should be 30b. :) PS. im not too good at math, so if thats wrong, please dont kill me!!

common terms are plus signs
so add the 2 plus signs14b+37b=+51b
than u take the minus sign-21b from the +51b=30b

30b
EXPLANATION:
b is the common unit between the three figures, so the problem can be evaluated using simple arithmetic...
14 - 21 = -7
-7 + 37 = 30
add the units "b" to the end, and you get the answer, "30b"
hope this helps!!

30b. If you are working on problems like this, you have heard the phrase "combine like terms". Thats what you need to do.
