why is 1-(-1/2)=1 1/2?

Answer 1

because the negative applied to a number reverses the sign, so:
- (+4) reverses the plus to -
- (-4) reverses the - to +

Answer 2

The part that reads -(-1/2) is equal to -1 x-1/2= 1/2 . When you multiply a negative number by a negastive number, you get a positive number, in this case a +1/2. So the statement is 11/2= 11/2 is true from what I told you.

Answer 3

1 - (- 1/2) = 1 1/2

1 + 1/2 = 3/2

1/1 + 1/2 = 3/2

2/2 + 1/2 = 3/2

3/2 = 3/2

1 1/2 = 1 1/2

- - - - - - - - - - -s-

Answer 4

When 2 negative integers come together they change into a positive (+) sign. So the question is= 1 + 1/2 = 1 1/2

Answer 5

its not, =1/2

Answer 6

if you do minus a minus you get plus. for example 2 - (-5) is the same as 2 + 5 so that is 7. The same is in your question 1 - (-1/2) is the same as 1 + 1/2 and that is 1 /2 or 1.5.

Answer 7

Consider some examples:-
Example 1
8 - 5 = 3
Think of this as how many steps from 5 to 8? The answer is 3 to the right, hence answer of 3.
Example 2
5 - 8 = - 3
Think of this as how many steps from 8 to 5? The answer is 3 steps to the left, hence answer of - 3
Example 3
5 - (-3)
How many steps from (-3) to 5. Answer is 8 steps to the right , hence answer of 8.
This can be got by saying 5 - ( -3) = 5 + 3 = 8
Thus 1 - (-1/2) = 1 + 1/2 = 1(1/2)
Hope these examples help.

Answer 8

Subtracting a negative is the same thing as adding a positive, so the total is 1 1/2.

Answer 9

Because two negatives equals a positive, so the question is really 1 + 1/2.

Answer 10

see ,there is a minus sign outside d braket,and deres a minus sign against 1/2,so if u follow the rule of integers,minus X minus equals plus.we do not put a plus sign, so it bcomes 1 1/2

Answer 11

Just remember " Two Wrongs Do make a Right."

A double Negative "IS" a positive.

Think of it like this, on the number line if you add a positive you move to the right. If you subtract a positive you move to the left.

If you add a negative you move to the left, and if you subtract a negative you move to the right.

If we now compare the two we see to subtract a negative and to add a positive both move to the right. This is why a double negative is the same as adding a positive.
