C =25-2 = ?
big number at the top |dw:1440698439999:dw| take out 2 from 5 what would you have left ?
|dw:1440698482678:dw| there is nothing under the 2 so carry down bigger number is positive answer would be positive as well so 25-2= ??
but we need -23 so C isn't correct
let's do B |dw:1440698571984:dw| negative sign front of parentheses is a police man parentheses is a door we can't open the door without shaking hand with the police man okay in math form i want to say you have to distribute parentheses by negative to remove the parentheses
so multiply -1(-14) = ??
yes right now |dw:1440698723359:dw| 14 -9 = ?
yes right but we need -23 so B isn't right now try A and D
11 – 34 so witch do i sub from 34 or 11
when both numbers are negative then you should `add` but keep the negative sign example `-2-3=-5` when you have two numbers one is positive and one is negative then ~if bigger number is negative answer would be negative (subtract) `-3+2==-1` ~if bigger number is positive then answer would be positive `3-2=1`
so 11-34 would you have to subtract 34 is greater than 11 so that would be at the top |dw:1440699034759:dw|subtract!
no reread my 2nd last comment if greater number is negative then answer would be ?
yes right what about D ?
d is zero
how ? would you add or subtract ?
if i give you 11 chocolates and another person give you 12 more would you get zero chocolates ?
no you would have 23
yes but both numbers are negative so answer would be ?
