A number added to -25 results in an even less value. Which of the following could be that
number? Select all that apply and model the situation to prove your choice(s).

a) 3
b) 2
c) 1
d)0
e)-1
f)-2
g) -3

E, F and G

Not A because: -25+3= -22 which is more than -25
Not B because: -25+2=-23 which is more than -25
Not C because: -25+1=-24 which is more than -25
Not D because: -25+0=-25 which is not less than -25
E because: -25+-1=-26 which is less than -25
F because: -25+-2=-27 which is less than -25 G because: -25+-3=-28 which is less than -25

No. While this is true in almost all cases, 2 and 4 are both factors of 4, while 8 is not.

For any other number, though, George is correct.
