that would be -6.5 right?

3. anonymous

so would it be -6-(1/2)?

4. campbell_st

it sees the negative associated with the 6 as an operator... same as when you input -3^2 you will get -9 as an answer

5. campbell_st

if you calculator has a fraction key... its easy ti input.

i guess my question is regarding to shortcuts. |dw:1346824704254:dw| 6 and a half. what we actually mean without the shortcuts is |dw:1346824730663:dw| But if we have |dw:1346824746385:dw| Do we mean -6 and a half as the shortcut? But |dw:1346824783677:dw|

when you have a negative it is ambiguous. I always just assume the whole number part is negative and so is the fraction part negative.

8. campbell_st

works for me... my calcuator allow me to input mixed numbers as factions...

$-6 \frac{1}{2}=-\left(6+\frac{1}{2}\right)=-\left(\frac{13}{2}\right)=-(6.5)=-6.5$
