      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.

    • @brennaandsebastian773
      @brennaandsebastian773 2 роки тому +2

      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
      @stringuserinputconsole.rea364 2 роки тому +1

      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.

      He added a negative sign for the whole bottom equation which would technically look like this 15- -28 and because two negatives equals a positive its 43. The way he wrote it looks confusing but its supposed to be a negative -28 and there's already a subtraction sign in between.
