The purpose of the ALU is to perform mathematical operations such as addition, subtraction, multiplication and division. Additionally, the ALU processes basic logical operations like AND/OR calculations. Also known as the arithmetic logic unit, it serves as the computational hub of the Central Processing Unit (CPU) for a computer system.
Continue ReadingAn ALU can be programmed to perform any series of complicated arithmetic or logical calculations. It is the computational capacity of the ALU that determines the power of a computer system’s CPU. In more complex systems, the ALU is divided into two units: the arithmetic unit (AU) and the logic unit (LU).

If there are parentheses, that operation is completed first. Any exponents are taken care of next. Multiplication and division operations follow exponents, but multiplication does not outrank division. Addition and subtraction come last, and they, too, have equal stature.
Full Answer >Basic operations with fractions involve addition, subtraction, multiplication and division. Addition and subtraction of fractions require a common denominator before making the calculations. When multiplying fractions, the numerators and denominators are multiplied separately to get the answer and when dividing fractions, the reciprocal of the divisor fraction is used, and the fractions are then multiplied.
Full Answer >Simple problems on math practice worksheets test the understanding of addition, subtraction, multiplication and division. More complex problems deal with concepts in geometry, fractions and measurement units.
