10 - 2 = 3
here's how, there are ten people at a party, 2 of them (a guy and girl) leave so they can be alone. nine months later, there are 3.

The concept of the derivative is fundamentally more advanced than the concepts encountered in algebra. In algebra, students learn about functions which input a number and output another number. For example, the doubling function may input 3 and output 6, while the squaring function may input 3 and output 9. But the derivative inputs a function and outputs another function. For example, the derivative may input the squaring function and output the doubling function.
To understand the derivative, students must master mathematical notation. In mathematical notation, one common symbol for the derivative of a function is an apostrophe-like mark called "prime". Thus the derivative of f is f ' (f prime). The last sentence of the preceding paragraph, in mathematical notation, would be written:
If f(x) = x², then f ' (x) = 2x.
The derivative of a function measures the slope of the function. If the input of the function is time, then the derivative measures the rate at which the function changes.
If a function is linear (that is, if the graph of the function is a straight line), then the function can be written f(x) = m x + b, where
.
This gives an exact value for the slope of a straight line. If the function is not a straight line, however then the change in y divided by the change in x varies, and we need calculus to find an exact value at a given point.
The slope, or rise over run, can be expressed as:
To determine the instantaneous rate of change we use the limit:
Working out one particular case, we find the slope of the squaring function at the point where the input is 3 and the output is 9.
The slope of the squaring function at the point (3, 9) is 6, that is to say, it is going up six times as fast as it is going to the right.
SO THE ANSWER IS 8.

what you meant to say was
(+10)(-2) = -20

that guy with the ridiculously long answer is probably right, but it could also mean ten wins and two losses, like in a sport.
