 exp3to5. 1st: Write your birth year. 2nd: Write the four digits of your birth year [ex. 1949 becomes 1, 4, 9, and 9]. 3rd: Using the digits of your birth year as 4 numbers, and using any operation you wish [+, -,, X, ÷, , 1/x, x (where x and n are two of the four numbers)] and as many parenthesis as you wish, write an expressions equal to each whole number from 0 to 10. Ex: 0 = (9 - 9)(4 - 1)

exp6.. Signed No. Connect-the-Dots

 equ7. The interval notations [a,b], [a,b), (a,b), and (a,b] each have different meaning because of the meaning of the (, ), [, or ] which indicate the inclusion or exclusion of the endpoints of the interval. (Notes on this topic are found at: Inequalities)   Use the endpoints 2 and 6. Write notes in words and with a number line to illustrate each of the four intervals 1st: State interval using the interval notation. 2nd: Draw a number line indicating the interval. 3rd: Describe the interval in English.
