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= 5x would be entered as " y=5∧x." 4. In the case of an expression use brackets. For example, y=(2x+7)2 should be typed " y=(2x+7)∧2"  5. No vector symbols are needed in your answers. For example 2uˉ+3vˉ would be typed as " 2u+3v ". 6. Other common symbols include: example x−33​ would be typed as " x/(x−3) ". Be sure to frame the numerator and denominator with brackets as necessary. - The " x " (multiplication or cross product) symbol, which should be typed as "**" (asterisk). For example <<u+5vˉ would be typed as "u"5v". - The " ​ " (square root) symbol, which should be typed as "root". For example y=x3+2​ would be typed as "root(x^ 3+2)′′. - The "П" (pi) symbol, which should be typed as "pi". For example -7П
