at the beginning of the week,stewart's checking account had a balance ofnegative $15.08. on monday morning, hedeposited a check for $426.90. on tuesday morning, he depositedanother check for $100. how much was in stewart'schecking account

How To Add Fractions Negative, after the second deposit, soafter both of these deposits right over here. so he starts off witha negative balance. so a negative balancemeans that he's

overdrawn his checking account. he actually owesthe bank money now. luckily, he's now going to putsome money in his bank account. so he'll actually havea positive balance in his checking account. so he's starts off withthe negative $15.08. and then to that,he adds $426.90. and then he adds another $100. so he started offwith negative $15.08.

and then to that, headds $426.90 and $100. so that's $526.90. and so how much is going tohave in his bank account? he started owing $15.08, andthen he's going to add $526.90. so one way to visualizeit is, if you think about it on a number line,if this is 0 right over here, he's going to startoff at negative $15.08. but then he's going to add $526. so this right over here,this is $15.08 to the left.

that's how much he owes. and to that, he'sgoing to add $526. so i'm not drawingthis to scale. but to that, he isgoing to add $526.90. so the amount that he's goingto be in the positive is going to be $526.90 minus the $15.08. it's essentially going to bethis length right over here. that's how much he's goingto be in the positive. and that's going to be$526.90 minus $15.08.

so that's going to be, andwe can even just rewrite this so it actually looksexactly like that. that's exactly the samething as $526.90 minus-- adding a negative is thesame thing as subtracting a positive-- minus $15.08. and this is-- i will dothis in another color-- $526.90 minus $15.08. let's see, 0 is less than 8. let's make that a 10and borrow from this 9.

so that becomes an 8, or i guessyou could say we're regrouping. now, everything up here islarger than everything there. so 10 minus 8 is 2. 8 minus 0 is 8. we have our decimal. 6 minus 5 is 1. 2 minus 1 is 1. and then you have5 minus nothing. so he is left with $511.82after his second deposit.
