Algebra is a way of working with numbers and signs to answer a mathematical problem (a question using numbers) As a single word‚ "algebra" can mean[1]: * Use of letters and symbols to represent values and their relations‚ especially for solving equations. This is also called "Elementary algebra". Historically‚ this was the meaning in pure mathematics too‚ like seen in "fundamental theorem of algebra"‚ but not now. * In modern pure mathematics‚ * a major branch of mathematics which

When you flip a light switch‚ the light seems to come on almost immediately‚ giving the impression that the electrons in the wiring move very rapidly. Part A: In reality‚ the individual electrons in a wire move very slowly through wires. A typical speed for an electron in a battery circuit is 5.0x10 to the -4th meters per second. How long does it take an electron moving at that speed to travel a wire 1.0
