Exponents

Review

• Evaluating exponents involves repeated multiplication

• If a number has an exponent of 2 it is referred to as being squared,

  • 3² you say "three squared"

• If a number has an exponent of 3 it is referred to as being cubed,

  • 4³ you say "four cubed"

Multiplying Decimals

• When you multiply decimals you do not line up the problem by the decimal points

• Starting from the right side of each number, count how many decimal places you have with each number

• Multiply as you usually would, starting from the right and working to the left

• Write down the amount of decimal places there are to the right of. the problem and circle it

Dividing Decimals

• Start by identifying the dividend and the divisor in your problem

• Rewrite the division problem using the division house with the dividend under the "house"

• Divide normally (think of how many times the divisor will go into the dividend)

• Bring up the decimal point into the quotient
