Function of digital computer A typical digital computer system has four basic functional elements: (1) input-output equipment. (2) main memory. (3) control unit. (4) arithmetic-logic unit. Any of a number of devices is used to enter data and program instructions into a computer and to gain access to the results of the processing operation. Common input devices include keyboards and optical scanners; output devices include printers and cathode-ray tube and liquid-crystal display monitors

Algebra has long been taught in the same way. This usually means teachers rely heavily on the textbook. Though some textbooks have changed in recent years‚ the central focus is till on paper and pencil‚ memorization of rules‚ and use of algorithms. The Curriculum and Evaluation Standards for School Mathematics (NCTM 1989) asks mathematics teachers to seek activities that “model real-world phenomena with a variety of function” and “represent and analyze relationships using tables‚ verbal rules

Quadratic Equations ax2 + bx + c = 0 Examples of Quadratic equations 1. x2 +2x – 8 = 0 2. x2 – 10x + 25 = 0 3. 3x2 + x - 2 = 0 Quadratic Formula If [pic] a x2 + b x + c = 0‚ then [pic] Finding the zeros of the quadratic functions - The zeros of a function are the input values which result in an output value of zero. One way of solving quadratic equations is using factoring Examples are the following: 1) x2 + 5x + 6 = 0 Set this equal to zero:

could be used in an accounting profession is combining like terms. Like terms are terms that have identical variables and exponents. Like terms must have exactly the same letter parts. Using like terms may not be exactly the same in accounting as in algebra‚ but it is the same concept. You can only add things to the same accounts; you cannot add a cash total balance to an insurance expense account. An example of combining like terms in accounting is having $600 spent on rent‚ $350 spent on supplies‚
