When adding positive numbers count to the right.

Why does a negative minus a negative equal a positive. For example -8 -2 4. However so that it works ALL the time and to get the clearest picture lets go back to 2 - 3. For example -3 minus 7 is -10.

What happens when you add a positive to a negative. Consequently what is the rule for adding and subtracting positive and negative numbers. When adding negative numbers count to the left.

Because minus a negative number is equivalent to plus a positive number. Basically a smaller more minus number is actually a bigger number with a minus sign in front of it. The fact that the product of two negatives is a positive is therefore related to the fact that the inverse of the inverse of a positive number is that positive number back again.

Then attach a minus sign to the result. When subtracting positive numbers count to the left. Basically -4 becomes 4 and then you add the numbers.

Subtracting a negative number is the same as adding a positive number that is go up on the number line. That 1 1 is 2 why is -1 - -1 not -2. Steves uncle cares about Steve and feels bad that he doesnt even have a 0 net worth.

When subtracting negative numbers count. 6 3 3 6 3 3 In other words subtracting a positive is the same as adding a negative. Atimes 0 0 and aleftbcrightabac.

In order for the result to be positive when subtracting a negative number from a negative number the number being subtracted has to be a smaller number more minus. Answer 1 of 9. The precise logical argument as to why negative times negative should be positive Once we agree that 2timesleft-3right-6 via repeated addition and left-3righttimes 2-6 via a belief in commutativity that negative times negative is positive is a forced logical consequence of these next two basic beliefs of arithmetic.

When taking a negative number minus a positive number drop both minus signs and add the two numbers as if they were both positive. But for your specific question of subtract a negative from a positive this works. So instead of subtracting a negative you are adding a positive.

So that each positive number would have an additive inverse. Basically - -4 becomes 4 and then you add the numbers. When you are adding a negative number to a positive number you are effectively subtracting the second number.

Why does a negative multiplied by a negative equal a positive. This is in fact the reason why the negative numbers were introduced. A negative minus a negative is equal to another negative number a positive number or zero depending upon the numbers in the equation.

The calculator interprets correctly by the way -32 as -1 times the square of 3. A negative number times a positive number equals a negative number. To answer this consider the simple multiplication 2 x 2.

He owes Michael 3. If the negative number being subtracted is the same as the number from which it is subtracted the answer is zero. Steve has a net worth of -3.

Two negatives make a positive so a negative number divided by a negative number equals a positive number. Subtracting A Negative Number. So instead of subtracting a negative you are adding a positive.

The fact that the product of two negatives is a positive is therefore related to the fact that the inverse of the inverse of a positive number is that positive number back again. If you recall PEMDAS we must consider the exponent before we consider multiplication. He has a negative net worth.

Subsequently What does a negative minus a positive equal. Subtracting a negative number from another negative number is the same thing as adding a positive number. If you mean why does your calculator give a result of -9 when you enter -32 I can explain that below.

It doesnt matter which order the positive and negative numbers are in that you are multiplying the answer is always a negative number. So he actually has a negative net worth. On a number line youd start with 2 then go left 3 times and your answer would be -1.

When you multiply a negative number to a positive number your answer is a negative number. For example say we have the problem -2 -. So these have the same result.

Ive never understood this. Just as subtracting a negative is. The answer to this question is accessible to a 7th grader and should in my opinion be explained as.

Why does a positive number minus a negative number equal a positive number. Subtracting a negative number from a negative number a minus sign followed by a negative sign turns the two signs into a plus sign. For example say we.

Subtracting a negative number from a negative number a minus sign followed by a negative sign turns the two signs into a plus sign. Because Im interested in finding out about negative numbers Im going to construct a situation in which I can start to investigate. Anyway enough about my experiences lets get onto the topic of the post.

Not only does he not have any money but he also owes Michael who is not depicted here. On the other hand subtracting a negative number from a positive number is equivalent to addition. If one subtracts a positive number from a negative number the process is still subtraction.
