9 x 1 = 9
9 x 2 = 18
9 x 3 = 27
9 x 4 = 36
9 x 5 = 45
9 x 6 = 54
9 x 7 = 63
9 x 8 = 72
9 x 9 = 81
9 x 10 = 90
9 x 11 =99
9 x 12 =108
In times tables, 3 x 3 = 9, and 1 x 9 = 9.
9 multipyed (times by) by 9 = 81 LEARN YOUR TABLES!!!!
No it isn't.
900
The 9 times table because 9*9 = 81 and 3*9 = 27
9, 18 etc.
40 times 9 = 360
No, it is not 9 x 5 = 45 9 x 6 = 54
The number 81 appears in several times tables. Specifically, it is found in the 9 times table (9 x 9 = 81) and the 3 times table (3 x 27 = 81). Additionally, it can be expressed in the 1 times table (1 x 81 = 81).
1, 3, 5, 9, 15 & 45.
For the 2, 4, 6, 8 times tables half it to 1, 3, 5, 7, 9 times table. MUCH Easier trust me!
Because certain times tables always end in particular numbers. The numbers in the 10 times tables always end with a 0 e.g 10, 20, 30... The number in the 5 times tables always end with a 0 or 5 e.g. 5, 10, 15... The 2, 4, 6, 8 times tables will always end in even numbers. The 1 times table is obvious. The 9 times table always has digits that sum to 9 e.g. 9, 18, 27... The hardest times table is usually considered to be the 7 times table to learn as their is no obvious pattern to the numbers.
