3 squared is 9, so asquare root of 9 is 3 It is like asking: What can I multiply by itself to get this? Definition Here is the definition: A square root of x isa number r whose square is x: r2= x The Square Root Symbol ...
By now, scholars had started routinely using seemingly nonsensical concepts such as imaginary numbers – the square root of a negative number – which don’t represent physical quantities in the same way that whole numbers or fractions do. No Victorian embraced these new concepts wholeheartedly, ...
Absolute Value Symbol To show we want the absolute value we put "|" marks either side (called "bars"), like these examples: |−5| = 5|7| = 7 The "|" can be found just above the enter key on most keyboards. More Formal

νits square, and so forth. Since there were no negative coefficients, the terms that corresponded to the unknown and its third power appeared to the right of the special symbol. This symbol did notfunctionlike the equals sign of a modern equation, however; there was nothing like the idea ...

That is, we simply juxtapose the multiplicands, without using any operator symbol. As we shall see in section 2.6, the geometric product AB is distinct from the dot product A·B and also from the wedge product A∧B. We further postulate that the geometric product is associative and ...
