3 - 10 = -7
once you get below zero the number adding start to go backwards and you always put a minus sign in front of it. it is called a negative sign.
-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10
that is the way the number line should look when counting below 0. the number of course go infinitely negative as they do psotive.
9/10 minus 3/5 is 3/10
10 minus -7 is the same as 10+7. So, 10--7=17.
3/10 minus 1/5 is 1/10.
x = 10 Minus 6 times 10 = minus 60 Add 3 to minus 60 = minus 57
6 and 7/10 minus 3 and 3/5 = 31/10 or 3 and 1/10
3/5 minus 3/10 is the same as 6/10 minus 3/10 = 3/10
9/10 minus 3/5 is 3/10
10 minus -7 is the same as 10+7. So, 10--7=17.

3/10 minus 1/5 is 1/10.
10 minus 3 and 2/5 = 7 minus 2/5 = 63/5
x = 10 Minus 6 times 10 = minus 60 Add 3 to minus 60 = minus 57
6 and 7/10 minus 3 and 3/5 = 31/10 or 3 and 1/10
n - 10 + 9n - 3 = 10n - 13
n - 10 + 9n - 3 n + 9n - 10 - 3 10n - 13
10 to the power 3 means 10*10*10, or 1000 10 to the power MINUS 3 means 1 over 10 to the power 3, so 1/1000.
19/20 minus 3/10 = 13/20
