Iam having trouble with multiplying negative numbers and positive numbers

So, negatives are tricky. But here's a nice rule for it:

1). negative (-) times negative (-) is positive because like signs, when multiplied are always positive.

2). negative (-) times positive (+) is negative because, different signs, when multiplied, are always negative.

3). positive (+) times positive (+) is positive because, again, like signs, when multiplied, are always positive.

Let's do the first 2 together:

So -5 times 7. First, let's ignore the signs and do the numbers first. 5 * 7 = 35. Cool. Now lets do the signs. Since it's a negative times a positive, it'll be negative. So your answer is -35.

Now lets do -8 times -4. Ignore the signs. 8 * 4 = 32. Now the signs. It's negative times negative. So it'll be positive because like signs, when multiplied, will always be positive. So the answer to the second one is 32.

Hope this helps!!

is it a purebred? it looks more like a red nose, but it doesn't have the red could it be a staffordshire bull terrior? unsure if that's the right name for it sorry

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
