positive and negative integers

What are Positive Integers?

Positive integers are all whole numbers greater than zero. They are typically written with or without a plus sign (e.g., 1, 2, 3, +4, +5, \dots). On a number line, they are located to the right of zero.

How do you add fractions with the same denominator?

To add fractions with the same denominator, you add the numerators and keep the denominator the same. For example: \frac{a}{c} + \frac{b}{c} = \frac{a+b}{c}

How do you add fractions with different denominators?

To add fractions with different denominators, first find a common denominator (the least common multiple of the denominators). Then, rewrite each fraction with the common denominator and add the numerators. For example: \frac{1}{2} + \frac{1}{3} The common denominator is 6. \frac{1 \times 3}{2 \times 3} + \frac{1 \times 2}{3 \times 2} = \frac{3}{6} + \frac{2}{6} = \frac{5}{6}

How do you subtract fractions with the same denominator?

To subtract fractions with the same denominator, you subtract the numerators and keep the denominator the same. For example: \frac{a}{c} - \frac{b}{c} = \frac{a-b}{c}

How do you subtract fractions with different denominators?

To subtract fractions with different denominators, first find a common denominator. Then, rewrite each fraction with the common denominator and subtract the numerators. For example: \frac{3}{4} - \frac{1}{2} The common denominator is 4. \frac{3}{4} - \frac{1 \times 2}{2 \times 2} = \frac{3}{4} - \frac{2}{4} = \frac{1}{4}

How do you multiply fractions?

To multiply fractions, you multiply the numerators together and multiply the denominators together. Simplify the resulting fraction if possible. For example: \frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d} And \frac{2}{3} \times \frac{4}{5} = \frac{2 \times 4}{3 \times 5} = \frac{8}{15}

How do you divide fractions?

To divide fractions, you multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is found by flipping the numerator and denominator. For example: \frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c} = \frac{a \times d}{b \times c} And $$\frac{1}{2} \div \frac{3}{4} = \frac{1}{2} \times \frac{4}{3} = \frac{1 \times 4}{2 \times 3} = \frac{4}{6} = \frac{2
