## Money Left - College Algebra

• 0:00 - 0:04
So we know that grant started off with a
certain amount of money from the venture
• 0:04 - 0:09
capital funders. But then he doesn't just
keep it, he starts to spend it. This means
• 0:09 - 0:13
that the right choice must take both of
these into account, the money that he was
• 0:13 - 0:17
given initially and the money that he
spent so far. The second and last choices
• 0:17 - 0:21
only have one of these two things each, so
that means that neither of them can be
• 0:21 - 0:26
right. So I'm going to cross them both
out. So that just leaves us with these
• 0:26 - 0:30
two. Money from funders plus money spent,
or money from funders minus money spent.
• 0:30 - 0:34
Spending money, actually takes away from
the amount of money that we have. It
• 0:34 - 0:38
doesn't add to it. So that means that the
third choice, right here, money from
• 0:38 - 0:42
funders minus money spent must be the
right answer. Now without even trying
• 0:42 - 0:47
we've actually just done some math. I know
that there aren't any numbers here, but
• 0:47 - 0:51
what we've created is called an equation.
It's called that because of this equal
• 0:51 - 0:55
sign right here in the middle. Over doing
with this equation is showing that these
• 0:56 - 1:00
two quantities, the one on the left side
of the equal sign and the one on the right
• 1:00 - 1:04
side. Are equal to each other, or have the
same numerical value. This is the first of
• 1:04 - 1:07
many, many equations that we're going to
look at throughout this course. And over
• 1:07 - 1:10
time you'll learn to do a ton of different
things with them.
