1. Leave no spaces between mathematical operators. For example, the line 2x + 5y = 10 should be typed in as "2x+5y=10." 2. Do not begin your solution with an equal sign. For example, the answer to the question "The sum of 2 and 5 is" should be typed in as "7", and not "=7". 3. The "A" (caret) symbol should be used to indicate exponents. For example, y = 5* would be entered as "y=5^x." 4. In the case of an expression use brackets. For example, y = (2x + 7)2² should be typed "y=(2x+7)^2" 5. No vector symbols are needed in your answers. For example 2ū + 3v would be typed as "2u+3v". 6. Other common symbols include: The "+" (division) symbol, which should be typed as "/" (backslash). For would be typed as "x/(x-3)". Be sure to frame the numerator and denominator with brackets as necessary. 3 example x-3 The "x" (multiplication or cross product) symbol, which should be typed as (asterisk). For example <<u+ 5V would be typed as "u*5v". The "V" (square root) symbol, which should be typed as "root". For example y = √x³ + 2 would be typed as "root(x^3+2)". ** The "TT" (pi) symbol, which should be typed as "pi". For example -711 would be typed as "-7pi".
