Addition of Integers Signs are the same Add and keep that sign Signs are different Subtract and keep the sign of the one which you have the most

Subtraction of Integers 1 st number stays the same Change sign to addition Change the following number to its opposite Use addition rules

Multiplication & Division of Integers Signs are the same Answer is positive Signs are different Answer is negative

Bar graph A bar graph displays date with vertical or Horizontal bars

Line Plots Use a number line an X’s

Histogram Shows the number of date. Items that occur with in each integral.

Line graph Line graph shows date that changes over time.

Stem an leaf plot Shows date arranged by place value

Circle graph Shows parts of a whole.

Box an whisker A graph that displays the highest and lowest quarters as whiskers the middle too of the data as the box and the median.

Scatter Plots It’s a graph with points plotted t show a relation ship between two sets of data.

Sale Price & Percent off Example: If a pair of jeans $62 at regular cot, nut is on sale for 20% off you would multiply $62 *.2 = $12.4 (this is how much they take off the cost if something is n sale) If you need the sale price(what you pay at the counter)you must Subtract the original cost- the amount taken off $62-$12.40=$49.60

Tax Example: Bob buys a TV for $125. He is changed 8% tax. How much tax did he pay? Multiple the $125 *.08=$10 tax If you want to find the total cost for the TV, add the original cost plus the tax. $125 + $10=$135

Interest Example: Cindy puts $500 in her savings account. She earns 4% interest for every year that she leaves the money in the bank. How much interest does she earn in 1 year? Multiply the $500*.04=$20 If you want the total amount she would get if she took her money out after one year, you must add the original amount to the interest. $500+$20=$520
