natural numbers can not be negative. integers can be both positive and negative.
The difference between two negative numbers is negative if the second number ( the number you are subtracting from the first) is less in value than the first. For example (-3) - ( -2) = -3 + 2 = -1 (-3) - (-4) = -3 + 4 = + 1
To idenify and write number sentence that moded numbers stories by using parentheses when more than one operation in involved.
Not necessarily. The difference between a = 7 & b = 7 is 0, and that is not a natural number.
