can u explain hoW 2 DO 71+-71=0?

Answer 1

Its the same as all the other questions you asked:
+ - = -
71-71=0

Answer 2

It's basically 71 - 71. Get your teacher to explain it, because it's hard to explain over the internet.

Answer 3

Here's the formula:
(+) + (+) = +
(-) + (-) = +
(+) - (+) = +
(-) - (-) = +

So it's like:
71 + - 71 = 0
(+71) (+0)(-0)(+71) = 0

Answer 4

well its fairly strait forward, the rule is:
when you add negative (-) and positive (+) to gether the asnwer will be the diffrence between them and it will have the sign of the biger, so 71+-70= -70+70 =70-70=0
hope you do understand

Answer 5

The guys above me have it right. I will give you a quick easy way to remember it though:

a plus sign has two lines - even
a minus sign has one line - odd

plus + minus = two lines + one line = three lines = odd

Because plus + minus = odd, it means it wil overall be minus

+- = -

Understand

Likewise, --=+
This is because one line+one line = two lines = even = +

If you understand what I mean, you will have no problem remembering!

Seems like you are struggling with this, since you have posted about five question about this. You could always have done that in just one by the way!

Answer 6

WOW!! You must have asked us to do at least 10 problems for you. The point is NOT can we explain; it is can YOU?? YOU are the one responsible for learning the material and taking quizzes and tests on the material. I hope you don't prepare for the test on heart surgery as you are for this one. You could kill a few people with your lack of knowledge. DO YOUR OWN WORK!! You are NOT asking for help!! You are asking someone else to cheat with you and do your work. At least value your character!!

Chow!!!
