In the video I cover adding decimals, subtracting decimals, multiplying decimals, and dividing decimals. When adding and subtracting decimals, the key is to keep the decimal places lined up. When multiplying decimals, you add up the total number of decimal places to get the answer. For dividing decimals, I quickly cover the situations of dividing decimals by whole numbers and dividing decimals by decimals.

The following problems are covered in the video:

Adding Decimals
→ 15 + 0.4 + .9251
→ 13.829 + 6 + .7

Subtracting Decimals
→ 17.912 – 4.5
→ 5.6 – 0.3991
→ 100 – 0.72

Multiplying Decimals
→ 1.2 × 11
→ 1.2 × 1.1
→ 12 × 1.1
→ .12 × 1.1
→ .12 × .11

Dividing Decimals
→ 2.67 ÷ 3
→ 2.67 ÷ 0.3
→ 2.67 ÷ 0.003
