Result

The result of your calculation will be displayed in the result box. The calculator will also show you the simplified form of the result if it's a fraction.

Formula Explained

The calculator uses standard arithmetic formulas to perform calculations with negative numbers and fractions. Here's a breakdown of how each operation is calculated:

Addition

a + b = c

Where a and b are the numbers you enter, and c is the result.

Subtraction

a - b = c

Where a and b are the numbers you enter, and c is the result.

Multiplication

a × b = c

Where a and b are the numbers you enter, and c is the result.

Division

a ÷ b = c

Where a and b are the numbers you enter, and c is the result.

The calculator automatically handles negative numbers and fractions by applying these formulas correctly. For example, when adding -1/2 and 3/4, the calculator will first find a common denominator and then perform the addition.

Worked Examples

Let's look at a few examples to see how the calculator works with negative numbers and fractions.

Example 1: Addition

Calculate -1/2 + 3/4.

Find a common denominator for 2 and 4, which is 4.
Convert -1/2 to -2/4.
Now add -2/4 + 3/4 = 1/4.

The result is 1/4.

Example 2: Subtraction

Calculate 5/6 - (-2/3).

Subtracting a negative is the same as adding a positive: 5/6 + 2/3.
Find a common denominator for 6 and 3, which is 6.
Convert 2/3 to 4/6.
Now add 5/6 + 4/6 = 9/6.
Simplify 9/6 to 3/2.

The result is 3/2.

Example 3: Multiplication

Calculate -3/4 × 2/5.

Multiply the numerators: -3 × 2 = -6.
Multiply the denominators: 4 × 5 = 20.
Simplify -6/20 to -3/10.

The result is -3/10.

Example 4: Division

Calculate 1/2 ÷ (-3/4).

Dividing by a fraction is the same as multiplying by its reciprocal: 1/2 × (-4/3).
Multiply the numerators: 1 × -4 = -4.
Multiply the denominators: 2 × 3 = 6.
Simplify -4/6 to -2/3.

The result is -2/3.
