First, to subtract fractions, you need to make sure that the both have a common denominator. By this, I mean that they need to have the same number on the bottom of the fraction. If they are not the same, you need to multiply. Say you had this problem: 4/5 - 1/3 You will notice they don't have a common denominator. To make sure that the bottom is the same number, multiply 4/5 by 3 and 1/3 by 5. When you multiply, you do this to both the top and the bottom number. The problem now looks like this: 12/15 - 5/15 Now you're ready to subtract! All you have to do is subtract the top numbers, and keep the bottom ones the same. So: 4/5 - 1/3 = 7/15
If you mean when you subtract a negative from a positive what does it make? If so, you will get a positive answer. This is because the two negative symbols are basically multiplied, and if you multiply two negatives you get a positive, so a positive number minus a negative number becomes a positive number plus a positive number. 6 - (-5) = 11 2 - (-10) = 12 125 - (-15) = 140
Using algebra the number works out as 25
The sequence alternates between multiplying by 2 and then subtracting 3. Starting with 5, you multiply by 2 to get 10, then subtract 3 to get 7, multiply by 2 to get 14, subtract 3 to get 11, multiply by 2 to get 22, and subtract 3 to get 19. Following this pattern, the next operation is to multiply 19 by 2, resulting in 38. Therefore, the next number in the series is 38.

2 and 5 if you multiply them. 50 and 5 if you divide them. 5 and 5 if you add them. 15 and 5 if you subtract them.
To subtract a number, re write the problem to add the opposite of the number. Example: 5-11 5+(-11) <-Rewrite the problem to add the opposite of the number. 11-5 <-Find the difference of their absolute values. 6 <-Subtract -6 <- -11has the greater absolute value, the answer takes the negative sign. hope this helps.

Convert the whole number to a fraction with the same numerator and subtract: 3-4/5 3=15/5 15/5-4/5=11/5
From the Fahrenheit temperature, subtract 32. Then multiply by 5/9.C = (5/9) (F - 32)From the Fahrenheit temperature, subtract 32. Then multiply by 5/9.C = (5/9) (F - 32)From the Fahrenheit temperature, subtract 32. Then multiply by 5/9.C = (5/9) (F - 32)From the Fahrenheit temperature, subtract 32. Then multiply by 5/9.C = (5/9) (F - 32)

x/3 + 5 = 11 Subtract 5 from both sides: x/3 = 6 Multiply both sides by 3: x = 18
