👉 Separate multiplication, or sep math, is a method of multiplying large numbers by breaking them down into smaller, more manageable parts. Instead of multiplying the entire number directly, you multiply each digit by the corresponding power of 10 based on its position (units, tens, hundreds, etc.) and then sum the results. For example, to multiply 123 by 45, you would calculate (123 × 40) + (123 × 5), which equals 4920 + 615 = 5535. This technique simplifies complex multiplications by leveraging the distributive property of multiplication over addition, making it particularly useful for mental calculations and handling large numbers efficiently.
