Question

simplify 1times 0 - 0 over y

Answer 1

do you mean
\[ 1 \times 0 - \frac{0}{y} \]

Answer 2

yea

Answer 3

like how would i work that out?

Answer 4

do you know order of operations ?

Answer 5

im havin a hard time rememberin bc this was from 9th grade an its been awhile im have to make it up bc i didnt do good enough on it

Answer 6

I've seen people use
PEDMAS

Parentheses (we don't have any in your problem)
Exponents (like \( 3^2 \) for example. we don't have those either)
Divide (we have that)
Multiply (we have that)
Add (we have this)
Subtract (we don't have this)

Answer 7

so you should do the divide first. that is 0/y

any idea what that is ?

Answer 8

how can you divide 0/y??

Answer 9

it helps to know it is the same as
\[ 0 \times \frac{1}{y} \]
and there is a "rule" zero times anything is what ?

Answer 10

0

Answer 11

yes, so 0 * 1/y or 0/y is 0

Answer 12

ok then it would b 1x0 -0

Answer 13

yes. Next we do the Multiply
1*0 is ?

Answer 14

0

Answer 15

yes
now you have
0 - 0

that is a Subtract, and the last operation we do.

Answer 16

so the answer would b 0.....thank you for helping me

Answer 17

yes.

the only thing you should be careful of, is if y was 0
then we would have 0/0 and that is not defined
so the "complete answer" would be
\[ 0 \ \text{ if } y \ne 0\\ \text{undefined if } \ y =0 \]

Answer 18

o ok thank you
