9 x 9 = 81 because if you count 9 times it would make up or be 81
9*9=81 81*100= 8100
1 times 81 3 times 27 9 times 9
81 is 72 more than 9 81 is 9 times 9
Because 9 times 9 equals 81.
How about: 9 times 9 = 81 or 81 times 1 = 81
9 x 9 = 81 because if you count 9 times it would make up or be 81
9*9=81 81*100= 8100
1 times 81 3 times 27 9 times 9
yes,9 goes into 81:9 times
81 ÷ 9 = 9
81
how do you not know it is of course cos 9 times 9 equals to 81
81 can be divided by 9 nine times. 9/81 = 1/9 (9 x 9 = 81)
9 times 9 equals 81. This is because when you multiply a number by itself, you are essentially squaring that number. In this case, 9 squared is equal to 81. This can be calculated by adding 9 to itself 9 times, or by using the multiplication operation to simplify the process.
81 is 72 more than 9 81 is 9 times 9
Because 9 times 9 equals 81.
