What this means is that multiplying by a negative number can be interpreted as repeated subtraction. A × 0 = 0 and a. You may get a negative sign in the resulting product’s numerator, and if so just put it in front of the entire fraction to show the answer more.

$\begingroup$ what @dougm wrote is technically true, but it should be qualified in the case of multiplying by zero. Take the positive number, and the negative without the minus sign, multiply them and add the inus sign to the product.

This is because multiplying some number by a negative number flips the sign. You may get a negative sign in the resulting product’s numerator, and if so just put it in front of the entire fraction to show the answer more.

Once we agree that 2 × ( − 3) = − 6 (via repeated addition) and ( − 3) × 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: Logically, it’s the only answer that makes sense.

We could have done it all with algebra but i personally prefer seeing a numerical example. The same is true for division as well.

No sudden superpowers or anything, but then again, no alien invasion either. So, if a positive number gets multiplied by a negative number, the positive number’s sign gets flipped to negative.

I hope that’s helped a little with understanding why a negative multiplied by a negative is a positive. So, our original negative sign is changed into a.

Once you’ve moved all those negative signs around and you’ve basically got negative signs all sensibly in the numerators, just go ahead a multiply the fraction just like you would normally. 5 rows negative multiplied by negative is a positive number, which means that the product of two.

Positive × negative = negative. We can also see here that a negative number multiplied by a negative number gives a positive number result.

I Hope That’s Helped A Little With Understanding Why A Negative Multiplied By A Negative Is A Positive.

No sudden superpowers or anything, but then again, no alien invasion either. Either when you multiply a positive number times a negative number or when you multiply two negative numbers so, for example you aren't quite sure what should happen if you were to multiply (and im just picking two numbers where one is positive and one is negative) what would happen if you were to multiply 5 times negative 3 you're not quite. For a case where a negative number is multiplied by a positive, the rule above can be restated as:

What Is A Negative Multiplied By A Negative?

It doesn’t matter which order the positive and negative numbers are in that you are multiplying, the answer is always a negative number. What this means is that multiplying by a negative number can be interpreted as repeated subtraction. A × 0 = 0 and a.

When Multiplying A Positive Number By A Negative Number And Vice Versa, The Result Give You Negative Answer.

We could have done it all with algebra but i personally prefer seeing a numerical example. Likewise, if a negative number gets multiplied by a negative number, the negative number’s sign will get flipped to positive. Actually, i just did this earlier today.

Since Multiplying By A Negative Number Is Repeated Subtraction, When We Multiply A.

The precise logical argument as to why negative times negative should be positive. We could also use the distributive property of multiplication to see if it fits with the results we have seen so far. Positive × negative = negative.

So, If A Positive Number Gets Multiplied By A Negative Number, The Positive Number’s Sign Gets Flipped To Negative.

$\begingroup$ what @dougm wrote is technically true, but it should be qualified in the case of multiplying by zero. And that’s why in the picture above, i show multiplication by a negative number with the arrows going backward. Ideally, the second negative should change the sign of our original number (which is also negative).
