Choose ANY 6 numbers. Add them together, and subtract 150 minus that sum, to get the seventh number. For example:0 + 0 + 0 + 0 + 0 + 0 + 150
1 + 2 + 3 + 4 + 5 + 6 + 129 = 150
1, 3, 5, 7, 9 and just keep adding two until you get to 149.
151
21/150 = 7/50 you get this by dividing both numbers by 3
126
Adding 150 250 times is the same as 150 x 250: 150 x 250 = 37,500

When subtracting negative numbers change the subtraction sign to a plus and change the second number (which would appear to be positive) to a negative. ex. -14 - 7=?/-14 + -7= -21 When adding negative numbers just add them as they appear. ex. -2 + -5= -7
You actually end up adding. Since a negative number is less than zero, subtrating negative numbers is really adding positive numbers. An example: 9 - (-7) = 9 + 7 =16.
