So, what would be the answer?

@amilapsn

remember our biker... Same logic applies here...

- amilapsn

Here's the logic.:
Start from zero.
Going up means plus(+)
Going down means minus (-)
Got that?

- anonymous

c?

- amilapsn

What you want to know is the sighn, ok?

- amilapsn

*sign

- anonymous

i got d

- amilapsn

not quite...

- anonymous

b sorry @amilapsn

- amilapsn

yep!

- anonymous

Without multiplying, determine the sign of the product (−247,634)(183,758).
The sign of the product is positive because a negative multiplied by a positive is a positive.
The sign of the product is negative because a negative multiplied by a positive is a negative.
The sign of the product is negative because the first number is negative.
The sign of the product is positive because the second number is positive.

- anonymous

b?

- anonymous

@amilapsn

- amilapsn

yep...

- anonymous

Multiply (3)(−4)(2).
−48
−24
24

Marlon withdrew $25 from his savings account every week for 5 weeks. Which expression is the best choice to help him determine the total amount of money he withdrew?
(25)(−5) = −125; he withdrew $125
(−25)(5) = −125; he withdrew $125
(−25)(−5) = 125; he withdrew $125
(25)(5) = 125; he withdrew $125

- amilapsn

yep you are correct....

- anonymous

@amilapsn

- amilapsn

withdraw means minus right?

- anonymous

yes

- amilapsn

So what do you think?

- anonymous

a?

- amilapsn

think again.... have you seen ..... ;)

- anonymous

is it either b or c?

- amilapsn

It can't be c, Can you say why?

- anonymous

um i dont know

- amilapsn

usually the terms cannot be minus values... they are always positive.... So 5 cannot be negative.... Got it?

- anonymous

got it! so b?

- amilapsn

hm.... yeah...

you can think it like this way:
Here's also the bicycle logic
\[\Huge\sf\color{blueviolet}{a\star b}\]
We always begin with zero...
Let's think we are on the zero.
first simply we go to the point a.
For example if a=5 we walk to 5.. if it's -5 we walk to -5
Then we've to consider the \(\color{blueviolet}{\star}\). It can be \(\color{blueviolet}{+}\) or \(\color{blueviolet}{-}\)
if it's + we don't have to turn
But if it's minus we have to turn back...
Then we have to consider about b
If its minus we move bakward the amount of b... let say b=-2.. then we move backward two units
if b is positive we just have to move forward the amont.
Got it....

- anonymous

so what would it be

- amilapsn

Can you please follow the steps and tell me the answer?

- anonymous

ok

- anonymous

a

- amilapsn

yep....

- anonymous

What number should be added to 17 to make the sum 0?

yep... !!

Use absolute value to express the distance between −10 and 16 on the number line.
|−10 − 16| = −6
|−10 − 16| = 6
|−10 − 16| = −26
|−10 − 16| = 26
