Multiplication and division, do you find them exciting? Especially long multiplication and long division! Well, whether you love them or not, they're key in KS3 Maths, so let's dive in and understand.
For long multiplication, we tackle the 10s, 100s, and 1,000s separately. For example, to calculate 154 x 23, multiply 154 by 3, then by 2 (add a 0 to the end), and finally, add the two answers. Resulting in 3,542.

The remainder becomes the first digit in the next number to divide. Continuing, divide 124 by 23, getting 5 remainder 9. Lastly, divide 92 by 23, resulting in 4. The answer is 154.
