A test for checking computations is called casting out nines. Consider the sum 612+301 + 500 = 1473 The remainders when 672, 301, and 500 are divided by 9 are 6, 4, and 5, respectively. The sum of the remainders, 15, has a remainder of 6 when divided by 9, as does 1473 Find the following sum and use casting out nines to check 398+476 + 182 398 476 182

Rate of Change

The relation between two quantities which displays how much greater one quantity is than another is called ratio.

Slope

The change in the vertical distances is known as the rise and the change in the horizontal distances is known as the run. So, the rise divided by run is nothing but a slope value. It is calculated with simple algebraic equations as:
