Example 2: negative − positive Lets subtract −4−7minus, 4, minus, 7. Step 3: Move 7 places to the left. We move 7 to the left because adding negative 7 decreases our number by 7. −4+(−7)minus, 4, plus, left parenthesis, minus, 7, right parenthesis takes us to −11 on the number line.

A mixed number is a whole number, and a proper fraction represented together. It generally represents a number between any two whole numbers. Look at the given image, it represents a fraction that is greater than 1 but less than 2. It is thus, a mixed number.

As stated before, finding the difference between two numbers, is just to subtract them. So if you want to find the difference, you take the bigger one minus the smaller one.

A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.

Then, adjust the fractions to have like denominators by multiplying the new fraction by the denominator of the original fraction. Subtract the numerators of the two numbers, and convert the answer to a mixed number if necessary. Remember to reduce the fraction if possible or divide it into a whole number.

Change the mixed number (with 1 as the whole number) into an improper fraction. Subtract the whole number of the smaller mixed number from the whole number of the new larger mixed number. If the proper fractions have similar denominators, subtract the numerators directly and remain the denominator as it is.

When adding negative numbers, count to the left. When subtracting positive numbers, count to the left. When subtracting negative numbers, count to the right.

Just take the absolute value of their difference, then, if larger than 180, substract 360° and take the absolute value of the result. If the direction doesn't matter (you want the one that yields the smallest value), then do the reverse subtraction (mod 360) and calculate the smallest value of the two (e.g. with Math.

["Rule 1: Adding positive numbers to positive numbers—it's just normal addition.", "Rule 2: Adding positive numbers to negative numbers—count forward the amount you're adding.", 'Rule 3: Adding negative numbers to positive numbers—count backwards, as if you were subtracting.']

Rule 3: Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. ... So we're changing the two negative signs into a positive, so the equation now becomes -2 + 4.

Subtracting Whole Numbers. To subtract whole numbers we write them as in an addition problem and subtract each digit moving from the right to the left. If when subtracting digits, the top number is smaller than the bottom, borrowing becomes necessary.

To do simple subtraction, use the - (minus sign) arithmetic operator. For example, if you enter the formula =10-5 into a cell, the cell will display 5 as the result.

Add a negative number. Adding normally moves to the right, but adding a negative number moves to the left instead. Start at +5, move 2 spaces to the left, and you end up at +3. So 5 + (-2) = 3. Here's another way to think of it: adding a negative number is the same as subtracting a positive number.

If the fraction parts of a mixed number have the same denominator and if we are subtracting a smaller fraction from a larger fraction, then the subtraction is straightforward: subtract the fractions and then subtract the whole numbers.
