-15. The rule is 'subtracting a positive is the same as adding a negative'
multiplying and dividing- positive * positive= positive positive * negative=negative negative *negative=positive subtracting- -3-6=? 1. freeze first number- -3 2.reverse the sign to a addition- -3+ 3.Reverse the sign of the number- -3+-6= -9 adding- keep the sign of the larger number, then add/subtract
-18. Subtracting a positive number has the same effect as adding a negative.
If you have negative 8 and subtract 3, you keep going backwards...so you get negative 11. or if you have negative 3 apples, and take away 3, then you have negative 6 apples. Subtraction of a negative number from another negative number can be positive For example: If you have negative three and subtract negative eight you get positive five. -3 - (-8) = 5
It doesn't always. 3 - (-3) = 6
Subtracting a negative number is the same as adding the corresponding positive number:6 - (-3) = 6 + 3Subtracting a negative number is the same as adding the corresponding positive number:6 - (-3) = 6 + 3Subtracting a negative number is the same as adding the corresponding positive number:6 - (-3) = 6 + 3Subtracting a negative number is the same as adding the corresponding positive number:6 - (-3) = 6 + 3

-3 - -1 = -2 -3 + -1 = -2 When you are subtracting a negative from a negative it becomes a positive. For example 6 - -2 = 8 but 6 + -2 = 4. The two negatives cancel each other out and become a positive.
-6 + -3 = -9. Note, adding a negative number is the same as subtracting a positive number, so the above equation could more efficiently be stated as -6 -3 = -9.
e.g. 'a' - ( -a) becomes a -- a a + a = 2a Here with a table for manipulating 'double' signs. = + = - = - = + NB If no sign is shown in front of a number , then read the number as plus(O).
