Do you know of any math problems that equal 9?

20 Answers

• There is an infinite amount of combinations to equal any number.

• 2+3+4=9

• 3 X 3 =9

• How about the super basic one:

  1 * 9 = 9

  2 * 9 = 18 (1+8 = 9)

  3 * 9 = 27 (2+7 = 9)

  ...and so on.

• 2+5+2 = 9

  9x3=27 and 2+7=9

  9x62 = 558; 5+5+8=18; 1+8=9

• The sort of questions you could come up with will depend on what level of math you're taking.

  However, the trick to creating a problem like the one you used as an example is to find a number whose digits will add up to 18, 81, 333, or 90 and which is divisible by 9.

  Hope that helps.

• 3 time 3 9#1

• Actually any multiple of 9 follows that same pattern

  3 x 9 = 27 , 7 + 2 = 9

  36, 54, 63, 72, 81, 90, etc.

• Well, there are millions of possible combinations what can equal 9.

  1*9=9

  3*3=9

  9/1=9

  81/9=9

  5+4=9

  square root of 81=9

  14-5=9

  1000-991

  There are millions of possiblities that you can try. Pretty much any number + or - another number can make nine.

• 9*6=54

  5+4=9

• 8x9=72

  7+2=9
