MAT 106 Midterm #3
No, because a-b does not equal b-a even though b-a = a + -b - ANS-Is subtraction
commutative, since addition is?
A positive times negative will always have a group of negative chips within the groups -
ANS-Why is a positive times a negative always negative?
The numerator is the shaded boxes, the denominator is the total amount of equal parts in the
entire rectangle - ANS-How can you see the numerator and denominator through the area
model?
No, division is the same as multiplying by the reciprocal of the second number - ANS-Is dividing
a number by 1/2 the same as taking half a number?
