Loading DocumentMultiplication in mathematics is using the repeated addition. Multiples of 9 are any number you get ( the products ) from multiplying 9 with integer ( whole number ).
Question
1 × 9 = ...
2 × 9 = ...
3 × 9 = ...
4 × 9 = ...
5 × 9 = ...
6 × 9 = ...
7 × 9 = ...
8 × 9 = ...
9 × 9 = ...
10 × 9 = ...
First Step
Write 0 at the left of multiplier number.
01 × 9 = ...
Second Step
Write 0 in the result ( at the right side of equal sign notation ) because every number multiple by 0 get zero. This zero number place in the tens number place value.
01 × 9 = 0 ...
Third Step
Multiply the multiplier number with multiplicand number. Write the nine.
01 × 9 = 09
Fourth Step
Write 0 at the left of multiplier number. in the second row result, write a number after the number from the previous row ( that is 1 ) as tens number place value. Then write a number before the number from the previous row ( that is 8 ) as ones number place value. So the result is eighteen.
01 × 9 = 09
02 × 9 = 18
Fifth Step
Write 0 at the left of multiplier number. in the third row result, write a number after the number from the previous row ( that is 2 ) as tens number place value. Then write a number before the number from the previous row ( that is 7 ) as ones number place value. So the result is twenty seven.
01 × 9 = 09
02 × 9 = 18
03 × 9 = 27
Next Step
Repeat the fifth step until all question rows is finished.
01 × 9 = 09
02 × 9 = 18
03 × 9 = 27
04 × 9 = 36
05 × 9 = 45
06 × 9 = 54
07 × 9 = 63
08 × 9 = 72
09 × 9 = 81
10 × 9 = 90
Result
Erase each zero in the first digit of multiplier.
1 × 9 = 9
2 × 9 = 18
3 × 9 = 27
4 × 9 = 36
5 × 9 = 45
6 × 9 = 54
7 × 9 = 63
8 × 9 = 72
9 × 9 = 81
10 × 9 = 90
