we learn in math class about integers. Positive and about negative integers. First we learn how to add integers, here some example for positive integer, first we have to know something
(+) + (-) = (-)
(-) + (-) = (+)
(+) + (+) = (+)

some example for positive integers



(+3) + (+9) = (+12)



(+5) + (+5) = (+10)



(+2) +( 4) = (+6)



(+4) + (+9) =(+13)



and then we do more positive integer



earn 30 doller lose 5 doller = left (+25) or 25 doller



have 5 orange lost 2 orange = left 3 orange






then we lern about how to draw integers time line I will show you time line pictures after first I want to show you how can we subtract integers, some example are



(-5) - (-9)



=(-5) + (+9) = (+4)



(-8) - (+6)



=(-8) + (-6) = (-14)



(-2) - (0)



= (-2)



Now I want talk about 0 pairs, some example for 0 pairs



(-6) + (+6) = (0)



(+100) + ( -100) = (0)



(+1000) + (-1000)= (0)



we did stenderd form in integers like



-2 -9 =-11



=+6 -7 = -1






-6 +2 - (-2)+ 3



=-6 +2 + (+2) +3



=-6 +7



=+1






we had quiz about negative and positive integers, like



(+9) + (+6) = (+15)



(+2) + (0) - (-4)



(+2) + (0) + (+4)



(+6)






(-5) - (-5)



= (-5) + (+5)



= (0)






(+6) + (+9) - (-4) - (-8)



=(+6) + (+9) + (+4) + (+8)



=(+27)


more about integers



rises 3 degree drop 2 degree = left 1degree



have 50 books give a friend 10 books = left 40 books




now I want to talk about time line, how can we add integers in time line



(+2) + (+1) = (+3) in time line

Good Job Azra. Just a couple of things you might have wanted to use some colour and you have lots of white space between each question.Also at the end you questions are squished together.

Good Job, but you could have made your writing a little bigger and explained your answers more.
