The pattern used to do addition is the same no matter how many digits are in the numbers or how many numbers you are adding together.

1. Stack the numbers according to place value.
2. Add the numbers in the columns starting with the column on the right.
3. Carry numbers into the next place value to the left as needed.
4. Repeat this pattern for each remaining column.

### Practice Problems

Evaluate the following expressions:
1. $$62 + 33 = ?$$ (
Solution
Solution: 95
Details:
One way to solve this problem is to think in terms of place values.

We have:
6 tens or 60
3 tens or 30
2 ones or 2
3 ones or 3

The following bars represent 6 tens. Each bar has 10 rectangles for a total of 60 rectangles. The following bars represent 3 tens. Each bar has 10 rectangles for a total of 30 rectangles. Now, add 6 tens plus 3 tens or $$60 + 30$$. Now, there are 9 tens, for a total of 90 rectangles. Then we can add our ones
$$2 + 3 = 5$$ or 5 ones The answer is 9 tens and 5 ones, which is 95. )
2. $$525 + 25 = ?$$ (
Solution
Solution: 550
Details:
Using place values, the problem $${\color{blue}525} + 25$$ is shown below. Start by adding the numbers in the ones column. The first answer is 10. Put the 0 in the ones column and carry the 1 into the tens column. Continue by adding the numbers in the tens columns. $$1 + 2 + 2 = 5$$
Put the 5 in the tens column. Finally, add the hundreds column. In this column, we have a 5 and nothing else. Hence the answer here is 5. The answer to $$525 + 25$$ is $$550$$.
