Question 4: Multiplication 4.1 Multiply by breaking up the second number: \( 245 \times 12 \)

To tackle \( 245 \times 12 \), you can break down the second number, 12, into its components: \( 10 + 2 \). This lets us do the calculations separately. So, first, calculate \( 245 \times 10 = 2450 \) and then \( 245 \times 2 = 490 \). Finally, add those results together: \( 2450 + 490 = 2940 \). Voila! \( 245 \times 12 = 2940 \). It’s like slicing a cake for easier servings! Using this method not only makes math easier but also helps to build mental math skills when you need to do calculations on the fly, like when budgeting for that cake you want to bake or counting friends at a party! Being able to break down numbers in your head is a handy tool that can save time and effort. Plus, you can impress your friends while you whip out numbers like a math magician!
