The

**equal addition**subtraction**method**. The**equal addition**subtraction**method**is also called the borrow and repay**method**, European subtraction, or**equal additions method**for subtraction. Today the**method**is used in Australia and Latin America.Besides, what is the lattice method?

The

**lattice method**is an alternative to long multiplication for numbers. In this approach, a**lattice**is first constructed, sized to fit the numbers being multiplied. If we are multiplying an -digit number by an -digit number, the size of the**lattice**is .How do you do a lattice multiplication?

**Steps**

- Draw a table with a x b number of columns and rows, respectively.
- Align the digits of the multiplicand with the columns and place it on top of the table.
- Create a diagonal path for the tables.
- Multiply the numbers using the distributive method.
- Start adding the numbers on the same diagonal paths.

What is a partial sum addition?

**Partial**-

**sums addition**is particularly useful for adding multidigit numbers. As the name suggests, a person using this algorithm first calculates

**partial sums**, working one place-value column at a time, and then adds all the

**partial sums**to find the total

**sum**.
