Addition of numbers with unlike signs: To add two real numbers that have unlike signs, subtract the smaller absolute value from the larger absolute value and associate with this difference the sign of the number with the larger absolute value.

To multiply a denominate number by a whole number, multiply the number part of each unit by the whole number and affix the unit to the product. To divide a denominate number by a whole number, divide the number part of each unit by the whole number beginning with the largest unit.

The rounding technique estimates the result of a computation by rounding the numbers involved in the computation to one or two nonzero digits. The clustering technique of estimation can be used when The distributive property is a characteristic of numbers that involves both addition and multiplication. The distributive property can be used to obtain exact results for a multiplication.
