Questions Covered in This Set
10 cards to master
How many characters can a positive grid-in answer use? A negative one?
Positive: up to 5 characters. Negative: up to 6 (the minus sign counts).
Are mixed numbers allowed?
No. Enter 5/2 or 2.5 instead of 2 1/2 — the machine reads '2 1/2' as 21/2.
Do fractions have to be reduced?
No. 4/8 is accepted anywhere 1/2 is accepted.
Which symbols are never allowed in a grid-in answer?
Dollar signs, percent signs, commas, units, and degree signs. $1,250 is typed as 1250.
What if more than one value satisfies the equation?
Enter just one of them. Never type something like '3,-5'.
How should you enter 2/3 as a decimal?
.6666 (truncated) or .6667 (rounded) — fill all available spaces. .67 is wrong.
Why start a decimal with a dot instead of '0.'?
Dropping the leading zero gains one more digit of precision within the 5-character limit.
Best rule of thumb for messy answers?
If the answer is a fraction, just enter the fraction — unless it's too long (e.g. 212/365), then use a filled decimal.
What does it mean if your answer contains a variable like 2x?
You haven't finished the problem — grid-in answers are always numbers, never expressions.
What is the most costly grid-in mistake?
Answering the wrong question — solving for x when the problem asked for 3x+1. Reread the last line before typing.
