As the final numeral, the number nine holds special rank. It is associated with forgiveness, compassion and success on the positive side as well as arrogance and self-righteousness on the negative.
The sum of the two-digits resulting from nine multiplied by any other single-digit number will equal nine. 9x3=27, and 2+7=9; 8x9=72, and 7+2=9, etc.
Here is a fun one to always help your child check their math problems when multiplying with the number 9. Multiply nine by any two, three or four-digit number and the sums of those will also break down to nine.
For example: 9x62 = 558; 5+5+8=18; 1+8=9.
Again, 9x597(any 3 digit number)=5373; 5+3+7+3=18 or 1+8=9
9x7,064(any4 digit number)=63,576; 6+3+5+7+6=27 or 2+7=9
A final example 9x9,999=89,991; 8+9+9+9+1=36 or 3+6=9
COOL stuff to teach your kids/grandkids, to then teach the teachers in a fun classroom project.
Enjoy the day . . . be a blessing to others.
