                          This lesson covers basic subtraction in the form of subtracting whole numbers. Students learn to subtract numbers with two or more digits, such as 985 - 47. The first step is to line up the numbers vertically so that the units digits are in the same column. Next, subtract the units digits, the tens digits, and the hundreds digits. When subtracting the units digits, notice that it is not possible to subtract 7 ones from 5 ones, so 1 ten must be borrowed from the tens column, leaving 7 tens and 15 ones. Now, subtracting the units digits, 15 - 7 = 8, subtracting the tens digits, 7 - 4 = 3, and subtracting the hundreds digits, 9 - 0 = 9. So 985 - 47 = 938. Note that the answer to a subtraction problem is called the difference, so the difference of 985 - 47 is 938.

                              This video shows us the rules for adding and subtracting measurements to show our level of accuracy. Note that the rules for addition/subtraction with significant figures are VERY different than the rules for mulitplication/division. Think about which number is the most precise!

                                                      This instructor in this video, Sal Khan, discusses adding and subtracting polynomials. In an easy, conversational tone, the instructor explains processes clearly. Mr. Khan uses the Paint Program (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education. The student or educator may want to open the video to 'full screen' as the instructor is using a black background and the writing is small.

                                                          Watch this video to learn how to identify linear and exponential functions from input output tables. Linear functions grow by equal differences over equal intervals so as x increases or decreases at a constant interval you add or subtract a constant for each corresponding y interval. Exponential functions grow by equal factors over equal intervals so as x increases or decreases at a constant interval you multiply or divide a constant for each corresponding y interval.
