16/20 - (-50/20) = 66/20 or 3 and 3/10
-20 and -20 10 and -50 40 and -80
The temperature difference between -30 degrees and 20 degrees is 50 degrees. Negative 30 degrees is 50 degrees lower than 20 degrees.
Negative 8 minus 12 is negative 20.
-13-(-50)= -13+50= 37
Actually I believe it is -116.5
It means that you really increase the number that you were subtracting from, because you are adding to it the opposite of the number that is subtracted. Think about your bank account. Let's say you withdrew $50 more than the amount of money that you had in your checking account. The bank statement will show a negative account of yours as - 50. If you deposit $30, then you can add 30 (which is the opposite of -30) to -50 to calculate your balance, or you can subtract -30 from -50, because from those "negative" money you took of some of them. So that, -50 - (-30) = -50 + 30 = -20 (your balance). Now, deposit $20 dollars more to subtract that -20 from your statement.
The negative integer of a debt of 20 would be -20.
65 + 65 + 65 + 90 + 90 + 90 + 90 + 50 + 50 + 50 + 50 + 50 + 50 + 20 + 20 + 20 + 20 + 20 + 20 + 20 = 995
20 + 50 = 70.
