Itself.
Depends. Add two positives and the sum is positive. Divide two positives and the quotient is positive. Multiply two positives and the product is positive. Subtract two positives and the difference could be positive, negative or zero. If the two numbers are the same, the difference is zero. If one number is larger than the other and we subtract the smaller from the larger, the difference is positive. Subtracting the larger number from the smaller one gives a negative difference.
could also be negative
It depends on what you do with the negative and positive. If you multiply or divide a positive number and a negative number, then the answer is negative. If you add or subtract a positive number and a negative number, the answer could be negative or positive depending on the numbers involved. If you put a negative sign in front of a positive number, the result is a negative number. If you put a positive sign in front of a negative number (like +(-7)), the result is still negative.
If you do -5+-5 you get -10 which is not a positive number. If you subtract two negative numbers you could get a positive depending on what number you are subtracting. E.G. -5 - -9 =4 which is positive. A good rule a thumb is -- goes up +- goes down.
The Answer could be neither positive nor negative because the positivve could be bigger than the negative or the neagative could be bigger than the positive
If you subtract a negative number from another number, you always get a bigger number. That is because minus a minus is a plus So you could subtract any negative number from 10 and answer is bigger than 10.
Divide by 2 and add half the difference for the higher number and subtract half the difference for the lower number. So you would have 23.2 +/- 1.6 giving 24.8 and 21.6.
Having learned how to do subtraction, he could subtract one number from another.
Multiply them by a number less than 1. Divide them by a number greater than 1. Add a negative number. Subtract a positive number. Any of the above will do. One could also reduce the font when printing the fraction.
the answer could be negative or positive depending on whether the negative number you're adding is bigger than the positive number
There are a number of things you could do to the small number: -- Add positive numbers to it. -- Subtract negative numbers from it. -- Multiply it by numbers greater than ' 1 ' . -- Divide it by numbers less than ' 1 '. -- Raise it to positive powers greater than ' 1 '. Repeat any of these steps until the small number grows to the size you want.
Some people find it easier to add or subtract whole numbers but yes, you could round to the nearest half.
