6 x 6 = 36, add 3+6 = 9
Add something to NINE to make it SIX IX is a Roman Numeral for 9 Add/ Prefix S to it to make it SIX
The next number would be 18.3, 4, 6, 9, 13To get from 3 to 4, you need to add one. To get from 4 to 6, you need to add two. To get from 6 to 9, you need to add three. And so on and so on.
Multiply 6 by 5 = 30 Divide it by 2 = 15 Add the 9 = 24
You make 3 equal groups of 2 in 9. Which would equal 6
You will add -3 to 9 to make it 6.
-3

6 x 6 = 36, add 3+6 = 9
9+(-3)=6 6-(-3)=9

-3 (minus 3)
Add -3 to 9 because 9+(-3) = 6 Alternatively add s to the Roman numeral of ix which is 9 which then becomes six.
You would add 9 to it.
You need to add 6 - (-9) = 6 + 9 = 15.
You can't add a letter. you add an integer (or a number).Adding -3 to 9 makes it 6.Another Answer:-It could be S because IX = 9 and SIX = 6
6 7/8+3 3/4=10 5/8first you add your 6+3 which is 9then you make the 3/4 a 6/8 so you can add the 7/8 which would equal 13/8That means you would have 9 and 13/8 but first you have to make the 13/8 a mixed number which would be 1 5/8 then you add that to the 9 from the beginning so..9 + 1 5/8 = 10 5/8
