…. Change subtraction to addition… but its not quite that simple. My bank account would *love* it if I could do that. If I *just* change the minus sign to plus, Im doing the opposite of what Im supposed to do.
Adding the OPPOSITE -- change two things –- Then were back in balance, and doing what the problem says to do. (The people who say change subtraction to addition expect you to remember to *also* change the sign of the number youre subtracting.)
Thats right, the rules havent changed. But we can think of this in a more advanced way – 6 – 2 = 6 + -2, which of course = 4 because same sign, add and keep different sign subtract! Keep the sign of the bigger number, Then youll be exact!
Opposites are … you know, not the same. Opposite. Backwards is not forwards. Theyre opposite. HOWEVER, its not like theyre just different, like cherry and pineapple. … if you turn around… and turn around again… youre going the same direction again. Yes is the opposite of no… but if you *refuse* to say *no* … then havent you really said yes?
Give these guys the bam! Bam! treatment… 6 – 550 - 25 10 – 340 - 20 10 – 410 – 5
If the new problems look like this, you have 100 % A + 6 + –550 + -25 10 + –340 + -20 10 + –410 + –5
