Problem solving with integer addition and subtraction

Which equation demonstrates how the number 346 000 can be partitioned?

2. Use partitioning to solve the equation: 723 000 + 15 000 =

3. Use partitioning to solve the equation: 456 000 - 132 000 =

4. Use partitioning to solve the equation: 158 000 + 26 000 =

5. Use partitioning to solve the equation: 738 000 - 156 000 =

The strategy involves rounding numbers to get an approximate answer.

The strategy involves rounding part of an equation to the nearest multiple of 10, 100, 1000, 10 000 or 100 000. Then, adjust for this rounding afterwards.

The strategy involves using partitioning to add and subtract.

The strategy involves using the column method to add and subtract.
