Explain why negative times a negative will result in positive answer?

I would do it but I'm not good at math and it's 12 right now, so quite frankly that won't increase the way I'm good at math....at all...actually it makes me quite worse.

Because if its the oppisite like...for example

bạn have a positive times a positive bạn get a negative
Now bạn have a negative times a negative and it will still be a positive
But if bạn have negative times positive hoặc positive times negative bạn would get a positive
The trick is that if there is a negative it will equal to a positive

If we can agree that a negative number is just a positive number multiplied bởi -1, then we can always write the product of two negative numbers this way:

(-a)(-b) = (-1)(a)(-1)(b) = (-1)(-1)ab

For example,

-2 * -3 = (-1)(2)(-1)(3)

= (-1)(-1)(2)(3)

= (-1)(-1) * 6

So the real câu hỏi is,

(-1)(-1) = ?

and the answer is that the following convention has been adopted:

(-1)(-1) = +1

This convention has been adopted for the simple reason that any other convention would cause something to break.

For example, if we adopted the convention that (-1)(-1) = -1, the distributive property of multiplication wouldn't work for negative numbers:

(-1)(1 + -1) = (-1)(1) + (-1)(-1)
    
(-1)(0) = -1 + -1

0 = -2

As Sherlock Holmes observed, "When bạn have excluded the impossible, whatever remains, however improbable, must be the truth."

Since everything except +1 can be excluded as impossible, it follows that, however improbable it seems, (-1)(-1) = +1.

Debt Debt is a good example of a negative number. One common form of debt is a mortgage in which bạn owe the bank money because the bank paid for your house. It is also common for an employer to deduct a mortgage payment from an employee's paycheck to help the employee keep on schedule with the payments. Suppose $700 is being deducted each tháng to pay the mortgage. After six months, how much money has been taken out of the pay for the mortgage? We can figure out the answer bởi doing multiplication. 6 * -$700 = -$4,200 This is an illustration of a positive times a negative resulting in a negative. Now suppose that, as a bonus, the employer decides to pay the mortgage for one year. The employer removes the mortgage deduction from the monthly paychecks. How much money is gained bởi the employee in our example? We can represent "removes" bởi a negative number and figure out the answer bởi multiplying. -12 * -$700 = $8,400 This is an illustration of a negative times a negative resulting in a positive. If one thinks of multiplication as grouping, then we have made a positive group bởi taking away a negative number twelve times.

It's all about theories and equation. If bạn can assume a+ b= c then that would be the same rule bạn apply with other problems like that. Hence like in the examples in your answer.
