# Thread: math homework that dosent make sense

1. ## math homework that dosent make sense

my question in my homework is:

29-1=30
In what way is that correct?

2. I'm confused aswell. What does the question ask? Does it ask if the statement is true or false?

3. $29 -1 \equiv 30 \: (\text{mod } 2)$

?

4. Hello, whipslasher

29 -1 = 30
In what way is that correct?
Looks like a joke from my childhood . . .

Write the numbers in Roman numerals, using matchsticks.

. . $XXIX - I \:=\:XXX$

Get it?

5. yeah i get it now, thanks!
