14 Addition and Subtraction Addition of whole numbers is easy but you need to keep your numbers lined up properly by place value.

15 Addition and Subtraction Addition of whole numbers is easy but you need to keep your numbers lined up properly by place value. For Example : Evaluate 1,234 + 581

16 Addition and Subtraction

17 Now add each column and carry if you need to…

19 Addition and Subtraction Now add each column and carry if you need to…

20 Addition and Subtraction Now add each column and carry if you need to…

21 Addition and Subtraction Subtraction also requires you to keep the place values lined up. Set up your problem and then subtract, borrowing if needed.

22 Addition and Subtraction Subtraction also requires you to keep the place values lined up. Set up your problem and then subtract, borrowing if needed. I like to use notebook paper on its side to use its columns to line up the place values…

30 Application Problems To really have an applied math course, we need to see where the math concepts relate to the real world. So where possible, we will look at real world examples of where the math is being used.

31 Application Problems To really have an applied math course, we need to see where the math concepts relate to the real world. So where possible, we will look at real world examples of where the math is being used. So we will need to learn how to read basic blue prints…

32 Application Problems In the figure below, you can see how linear dimensions are represented. 20 in 4 in

33 Application Problems In the figure below, you can see how linear dimensions are represented. Sometimes the dimension is listed inside the two markers along with the arrows that define that linear distance… such is the case with the 20 in. measurement. 20 in 4 in

34 Application Problems In the figure below, you can see how linear dimensions are represented. Sometimes the dimension is listed inside the two markers along with the arrows that define that linear distance… such is the case with the 20 in. measurement. 20 in 4 in There are other cases where the arrows and dimension value are too big to fit into the space. So the dimension value will appear inside, and the arrows will appear outside and squeeze in towards the dimension’s value.

35 Application Problems Some figures will have holes shown. The holes will have the center marked with a plus sign, and lines extending from that center out a little beyond the edge of the circle.

36 Application Problems Some figures will have holes shown. The holes will have the center marked with a plus sign, and lines extending from that center out a little beyond the edge of the circle. Distance between holes will be shown as center to center. 14 cm

37 Application Problems Some figures will have holes shown. The holes will have the center marked with a plus sign, and lines extending from that center out a little beyond the edge of the circle. Distance between holes will be shown as center to center. Distance from an edge or from other parts of the figure will also be shown to center of given circles. 14 cm 50 cm

38 Application Problems Some figures will have holes shown that are equally spaced apart.

39 Application Problems Some figures will have holes shown that are equally spaced apart. A horizontal or vertical line will run through the centers to show their centers will all be on the same line.

40 Application Problems Some figures will have holes shown that are equally spaced apart. A horizontal or vertical line will run through the centers to show their centers will all be on the same line. There will also be a vertical or horizontal lines through each circle to show center.

41 Application Problems The number of holes will also be shown… 8 holes equally spaced apart
