This video tutorial covers the fifth-grade math standard of operations with decimals, focusing on adding and subtracting decimals. It explains the process of aligning decimal points, filling in gaps with zeros, and performing arithmetic operations. The video also addresses carrying and borrowing techniques, emphasizing that these processes are similar to those used with whole numbers. Through various examples, the tutorial demonstrates how to handle different scenarios, including borrowing with zeros, ensuring students understand the importance of place value alignment.

What is the first step in adding or subtracting decimals?

• Add zeros to the numbers

• Align the numbers by the decimal point

• Start adding from the left

• Subtract the smaller number from the larger one
