Negative numbers help us to model many real world situations. ** **3.3A. Decribe any pattterns yo observe in the way he differances change as the integers subtrate from 15 get smaller. As the number of integer gets smaller the numbr goes up.

3.3B. Use the patterns you observed to predict the anwser 15-(-1). check your prediction. the answer is 16 because -- = a positive + so its 15 + 1= 16

3.3C. Predict the answer to 15-(-4) the answer would be 19 because two negitives = a positve so its 15+4=19

How do i find the difference in integers?

Question 1: find the pattern -10+3 -10+4 -10+5 -10+6 So this is the Number line for the first pattern [+3-] = -7 [+4] = -6 [+5---] = -5 [+6--] = -4

<-> The pattern is going up by 1 -10 -9 -8 -7 -6 -5 -4 -3 -4 -3 -2 -1 0 This number line is one of the ways we where showed in class how to find the patterns Question 2: 10-(-3) 10+3=13 10-(-4) 10+4=14 10-(-5) 10+5=15 10-(-6) 10+6=16**
