Nicklaus' Integers Post

(If you see any mistakes, please comment)

I will label the 3 columns A,B,C. A is the left column, B is the middle column and C is the right column. I also label the rows 1-11.  I will just put the column letter and the the row number in my questions.

Question (A,4)
(-5) + (-3) = (-8)    
(because I am in Mr. Harbeck's class, I need to put the "have" and "owe" on every question. So here I go)

Owe 5 and owe 3 = owe 8

( I also have to put it into integers chips [ i don't know what you call those chips] and or to a number ling)

 Nice there are no Zero pairs, I just added all of the negative chips

 Question (A,8)
9+(-6)=3
Have 9 and owe 6 = have 3

Since there are zero pairs, i simply circled all of the zero pairs and count how many positive or negative chips there is left which in this case, there are 3 positive chips left.

Question (B,6)

8-(-7)=15

have 8 remove owe 7 = have 15

 (sorry i cant do this one on paint because there is not that much space to do this on paints)

+ + + + + + + +            - - - - - - -

+++++++                      +++++++

Question (B,7)

(-6)-9=(-15)

owe 6 owe 9 =owe 15

Question (B,9)

2-(-5)=7

have 2 remove owe 5=7 ( i added because 2 negative makes a positive so - -7 =+7)

Question(C,1)

8-(-2)= 10

Have 8 remove owe 2 =10

                                     

Nicklaus' multiplying integers scribe

Question #5
Write each repeated addition as a multiplication.
 A)   (+1)+(+1)+(+1)+(+1)+(+1)= 5 * 1 = 5
 B) (-6)+(-6)= 2 * -6 = -12

Question #7

 Write each expression as a repeated addition.

A)  (+3)*(+8)= (+8)+(+8)+(+8)= (+24)

B)  (+5)*(-6)= (-6)+(-6)=(-6)+(-6)+(-6)= (-30)

Question # 13

Copy and Complete each multiplication statements.

A) (+4)*(+6)= (+24)   

B) (+7)*(-2)= (-14)

C) (-1)*(+5)= (-5) 

D) (-8)*(-2)=(+16)

Question # 15

An aircraft descends at 3 m/s for 12 s. Use multiplication to represent the situation.  How far does the aircraft descend?

3*12= 36     The aircraft descend 36 m.

Question # 17

An oil rig is drilling 2 m/min. How deep is the well after the first 8 min?

2*8=16    The well is 16 m deep.
