Why does it not give you the answers? How am I supposed to check if I'm right or not? Quite annoying...

Very throrough but also easy to understand

algebra have been my favorite during my days in high school

math is one of the hardest courses for me to learn and I don't know why.

(a+b)(a-b)= a2-ab+ab+b2

* is number of boxes for apples.
a is number of apples in each box.
n2 is number of boxes of bananas.
b is number of bananas in each box.
n3 is number of boxes of pears.
p is number of pears in each box.
T is total number of fruits.

a+p+b+o= b=a+p+o= Every side divide by b then you can get the result of B.
