find a-root b
​

Answer 1

Answer:

By convention you should either not write a multiplication-sign at all, as in y=mx+cy=mx+c; or you should write it using a vertically centered dot, as in 3⋅5=153⋅5=15. Do not use symbols like "*"! In LaTeX you use the command \cdot to make a multiplication-dot.

Sometimes you can use the symbol ××. A matrix having nn rows and mm columns is a m×nm×n-matrix. The code \times is used in LaTeX to make the symbol ××.

The square root symbol is written using the command \sqrt{expression}. The nn-th root is written using the command \sqrt[n]{expression}.

The square root of a number can never be negative by definition. The root of a quadratic equation however, can be either positive or negative. The solution to the equation x2=4x2=4 is given by x=±2x=±2. The symbol ±± is written using the code \pm in LaTeX.

To write a fraction, you use the code \frac{expression in the numerator}{expression in the denominator}.

Formulas that appear in text are called inline. Inline formulas are sometimes squashed to avoid altering the height of the lines. Squashed fractions may look strange, and for that reason there is a special command to force a fraction to appear as displaystyle even though it is inline; the command is \dfrac.
