Why do i need to add a parantheses in my calculater to get 43 ? If i do it the basic way it gives me -13

[@puglifeforever8345]

The parentheses tell your calculator what to do first. Without them it might mess up the order and give a different answer

Thanks you so much I need this for a test thx

[@stevenscottoddballz]

I need help please. [X+Y=188 and X-Y=34] When I isolate X, I get X=188-Y. When I put it in the other equation, I get: [188-Y-Y=34], then [-2Y=-154], which gives me the final answer of [Y=77]. BUT when I try to isolate Y, I get [Y=188-X], and when I put it in the other equation, I get [X-188-X=34], but this will give [-188=34], which is false. How do I fix that?

[@masterhalo7677]

question: why would the -28 + the postive 15 = a negative 43 is that a rule or....?

[@brennaandsebastian773]

he didnt say that because thats not valid it must've been subtracted or added a negative, but -28 plus +15 is not equal to 43, but -28 plus -15 is, you mustve mis-seen.

[@stringuserinputconsole.rea364]

The reason for that is 15-(-28) if you remember the sign rules they'll be added to each other the minus sign next to 15 can also be considered negative or minus what ever you call it, but one thing for sure is that if both two negetive sign face's each other the number beside them should be added and remain as negatives. Yes the sign beside 15 is the arithmetic operation which is called a minus sign, and they really not that far from each other cause they can be either called a negative sign or a minus but we usually refer minus as an arithmetic operation and an negative to to identify if its a negative number.

how did u get 43 at 2:49? double negative? wouldn’t it just be 15- -28. HELP I HAVE MCAS TMR

[@haseebbbb]

if you subtract a negative, its just adding the number. for example, 25 - -1 = 26, or you can just do 25 + 1.

[@kamiyal]

literally saving my college degree sophomore year

[@nucavani]

It’s 15y - negative 28 y sir! @2:57. Should watch ur videos before posting can be super confusing for some! Cheers

[@wingman4117]

He is subtracting both sides, not adding them. A double negative is positive, so negative 28 turns into 28 and you subtract seven from negative 36. This turns into what he wrote down.

[@floyd3930]

I sort of get. But why is 5y and -4 a 15y? And why is -12 and 1 a 36? I would think that would be -20 and -12. But if not,could you explain some more?

[@DwayneTheWokJohnson1]

I'll try to explain it. so he was multiplying the top equation by 3 and the bottom one by 7. so he wasn't multiplying 5y and -4y, he was multiplying 5y and 3 to get 15y. and for the other confusion, he wasn't multiplying -12 and 1, he was multiplying -12 and 3, making it -36
