 If the limit implicit multiplication option is activated, the use of implicit multiplication when parsing expressions and displaying results will be limited to avoid confusion. For example, if this mode is not activated and <span class="quote">“<span class="quote">integrte(5x)</span>”</span> is accidently typed instead of <span class="quote">“<span class="quote">integrate(5x)</span>”</span>, the expression is interpreted as <span class="quote">“<span class="quote">int(e × e × (5 × x) × gr × t)</span>”</span> (displayed in history window). The result will then without any error be <span class="quote">“<span class="quote">int(2.3940139x × km^2)</span>”</span> instead of <span class="quote">“<span class="quote">2.5x^2</span>”</span>. If limit implicit multiplication is activated, the mistyped expression would instead show an error telling that <span class="quote">“<span class="quote">integrte</span>”</span> is not a valid variable, function or unit (unless unknowns is enabled in which case the result will be <span class="quote">“<span class="quote">5 "integrate" × x</span>”</span>). When implicit multiplication is limited, variables, functions and units must be separated by a space, operator or parenthesis (<span class="quote">“<span class="quote">xy</span>”</span> does not equal <span class="quote">“<span class="quote">x × y</span>”</span>).
