Long Multiplication โ๏ธ
To multiply bigger numbers, multiply by the ONES digit, then the TENS digit, and add the two rows. Take 23 ร 14. Start with the ONES digit: 4. Go digit by digit. 4 ร 3 = 12 โ write the 2, carry the 1 above the next column.

24 ร 2 = 8, plus the carried 1 = 9 โ write 9. First row is 92.
2 3 ร 1 4 ----- 9 2
Now the TENS digit: 1. It really means 10, so put a 0 in the ones place first.

9 2
0Then 1 ร 3 = 3 and 1 ร 2 = 2. Second row is 230.
2 3 ร 1 4 ----- 9 2 2 3 0
Add the two rows: 92 + 230 = 322.
2 3 ร 1 4 ----- 9 2 2 3 0 ----- 3 2 2
Don't forget the carry: whenever a digit ร digit is 10 or more, write the ones and carry the tens above the next column.
23 ร 4 = ?
