anonymous · Answer

after subtracting, i ended up getting 25190, but since you had to round to the hundreds, my answer came out to be 2520

anonymous · Answer

unfortunately, my answer is incorrect. can anyone tell me what did i do wrong?

aaronq · Answer

In "4659¯0", what does the " $^-$ " mean?

anonymous · Answer

it's just a bar, meaning it's in the tenths place

aaronq · Answer

so it's like a decimal point?

anonymous · Answer

the bar is on top of the number 9

anonymous · Answer

i guess

aaronq · Answer

4659.0−214.00, is this equivalent to what you have?

anonymous · Answer

answer wise? or questions wise?

aaronq · Answer

question-wise

anonymous · Answer

question*

anonymous · Answer

it has the bar instead of the decimal point

aaronq · Answer

4659.0−214.00=4445

you had 5 sig figs initially, so 4445.0

anonymous · Answer

hmm let me try

anonymous · Answer

there's a hint option. it gives you a question that asks" 4659¯0 has the final significant digit in the tens place and 214¯00 has the final significant digit in the hundreds place. To what place will the final answer be rounded?"

anonymous · Answer

the answer came out to be hundreds

anonymous · Answer

so the answer should be 4450?

aaronq · Answer

if you're keeping the amount of sig figs, it should be 5 sig figs.

aaronq · Answer

the answer doesn't need to be rounded because they're all integers

anonymous · Answer

i got it wrong

anonymous · Answer

but thanks anyway

aaronq · Answer

4450.0 is not the answer?

anonymous · Answer

nope

aaronq · Answer

what is the answer?

anonymous · Answer

i got two more attempts

aaronq · Answer

i see. that's odd, though.

anonymous · Answer

yeah..

aaronq · Answer

maybe it's the bar, i don't know if were interpreting it right.

anonymous · Answer

thanks anyway

aaronq · Answer

sorry, dude. Maybe ask in the math section?

anonymous · Answer

alright, i"ll try.

anonymous · Answer

The bar on top means the numbers on the left of it are significant including the one with the bar . You take the one with the least amount of significant numbers.
214¯00 -> You round the answer at the hundreds.
so 46 590 - 21 400 = 25 200
if its for mastering chemistry, i tried it and it worked :)
