Negative/negative=Positive (they cancel out)
negative/Positive=negative
negative X negative = Positive (they cancel out)
negative X Positive = Negative
when adding the negatives will not cancel. If the negative number is bigger the it will = a negative and Viceversa
Take note:
i) Negative + Negative = -(Add the two numbers)
Example:
-10 + -3 = - (10+3)
= -13.
Therefore: -8 + -3 = -11. ( Just add the two numbers and put the minus sign).
ii) Small number - Big number = - (big number - small number).
Example:
3 - 5 = - (5-3)
= -2. (just subtract the small number from the big number and add the minus sign)
Example: 1 -7 = -6. Using same logic.
y= -2/7x + 5
