Journal Entry 2: "Unlike Terms"

X is different than x^2, because they are different terms and one of them is squared.
Example you have a rat and a cow, you can not add both of them because they are two
different kinds of animals.We can combine terms that have the same exponent, because
they both have the same terms. Example you have two cow and then another cow shows
up, that means now you have three cows.They are called like terms, in order to add and subtract integers you need to circle the like terms.Yes 8m-2m is the same of 8m+-2m
because they have the same term which m.

"Like Terms"

The definition of like terms are terms with the same variable raised to the same power. 100p
and 300p are like terms, because we can combine them to get 400p. P and p2 are not like terms,
because we can't combine them, 1 is squared. We can't combine 2d+2f, because they have different variables. No an expression can not have an equal sign,because an equation does not equal.

Moving Variables

We move one variable term to the other side of the equal sign by using the inverse operation,for example the opposite of addition is subtracting.For the problem 16j=12-4j I would add 4j because
the inverse operation of subtracting is addition, so I would add 4j on both sides.The relationship between subtraction and addition is that they are the opposite of one another.The phrase "What
we do to one side we must do to the other side" relates to the balance scale, because if you have
a problem like 24j=12-4j, you must add because you have to do the inverse operation of the problem which is adding so then you add 4j on both sides,24j+4j and 4j+4j.
