## How do you add fractions step by step?

To add fractions there are Three Simple Steps:

1. Step 1: Make sure the bottom numbers (the denominators) are the same.
2. Step 2: Add the top numbers (the numerators), put that answer over the denominator.
3. Step 3: Simplify the fraction (if needed)

How do you add and subtract Monomials?

To add two or more monomials that are like terms, add the coefficients; keep the variables and exponents on the variables the same. To subtract two or more monomials that are like terms, subtract the coefficients; keep the variables and exponents on the variables the same. on the variables the same.

How do you simplify fraction?

How to Reduce Fractions

1. Write down the factors for the numerator and the denominator.
2. Determine the largest factor that is common between the two.
3. Divide the numerator and denominator by the greatest common factor.
4. Write down the reduced fraction.

### How do you add and subtract mixed numbers?

The steps are the same whether you’re adding or subtracting mixed numbers:

1. Find the Least Common Denominator (LCD)
2. Find the equivalent fractions.
3. Add or subtract the fractions and add or subtract the whole numbers.

Do you add or subtract exponents when dividing?

To divide exponents (or powers) with the same base, subtract the exponents. Division is the opposite of multiplication, so it makes sense that because you add exponents when multiplying numbers with the same base, you subtract the exponents when dividing numbers with the same base.

What is the rule for adding exponents?

To add exponents, both the exponents and variables should be alike. You add the coefficients of the variables leaving the exponents unchanged. Only terms that have same variables and powers are added. This rule agrees with the multiplication and division of exponents as well.

#### How do you add and subtract fractions with different denominators?

Make their denominators equal using the concept of least common multiple. Then subtract their numerators accordingly. Rewrite each fraction to its equivalent fraction with a denominator equal to the LCM = 30, then subtract their numerators. Make sure to reduce your answer to the lowest term.

How do you add fractions with different denominators step by step?

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

What are the different concepts in subtracting polynomials?

Answer: There are two methods for subtracting polynomials: the horizontal and vertical methods. Both methods work equally well, you can choose which method you are more comfortable with. It’s important to combine like terms and keep track of the negative and positive signs when subtracting polynomials.

## How do you add and subtract polynomials?

The same symbols are used. You add polynomials when there are plus signs. You subtract them when there is a minus sign. Remember to only add/subtract like terms within the polynomials.

Do you add or multiply exponents?

To multiply two exponents with the same base, you keep the base and add the powers.

What is the rule for subtracting exponents?

If both the exponents and the bases are the same, you can subtract them like any other like terms in algebra. For example, 3y – 2xy = x y.

### What is the negative exponent rule?

What is negative exponent? A negative exponent helps to show that a base is on the denominator side of the fraction line. In other words, the negative exponent rule tells us that a number with a negative exponent should be put to the denominator, and vice versa.

How do you subtract fractions step by step?

There are 3 simple steps to subtract fractions

1. Make sure the bottom numbers (the denominators) are the same.
2. Subtract the top numbers (the numerators). Put the answer over the same denominator.
3. Simplify the fraction (if needed).

How do we add two polynomials?

1. Start with:2×2 + 6x + 5 + 3×2 − 2x − 1.
2. Place like terms together:2×2+3×2 + 6x−2x + 5−1.
3. Which is:(2+3)x2 + (6−2)x + (5−1)
4. Add the like terms:5×2 + 4x + 4.

#### How do you find a common denominator?

To make the denominators the same we can: Multiply top and bottom of each fraction by the denominator of the other. We simplified the fraction 2032 to 1016 , then to 58 by dividing the top and bottom by 2 each time, and that is as simple as it can get!

What is the rule for adding and subtracting exponents?

To add or subtract with powers, both the variables and the exponents of the variables must be the same. You perform the required operations on the coefficients, leaving the variable and exponent as they are.

What are the five rules of exponents?

Exponent rules

• Product of powers rule. When multiplying two bases of the same value, keep the bases the same and then add the exponents together to get the solution.
• Quotient of powers rule.
• Power of a power rule.
• Power of a product rule.
• Power of a quotient rule.
• Zero power rule.
• Negative exponent rule.

## Can you add bases with different exponents?

multiplying exponents If exponents have different bases, you cannot add their powers. If the exponents have coefficients attached to their bases, multiply the coefficients together. If exponents have the same power and the same base, you can choose either method to simplify.

How do you solve negative fractions?

– The negative of a number can be created by multiplying the number by negative one. Placing the negative sign before the entire fraction (subtracting the fraction) is equivalent to adding the same fraction, but with a negative numerator.

What are the six laws of exponents?

• Rule 1 (Product of Powers)
• Rule 2 (Power to a Power)
• Rule 3 (Multiple Power Rules)
• Rule 4 (Quotient of Powers)
• Rule 5 (Power of a quotient)
• Rule 6 (Negative Exponents)
• Quiz.
