Markus Burns💠 Learn to solve the following problem by breaking it into several parts:
24 ✖️ 16
Step 1. Break the problem into easier parts:
20 x 10 = ?
20 x 6 = ?
4 x 10 = ?
4 x 6 = ?
Step 2. Solve each part:
20 x 10 = 200
20 x 6 = 120
4 x 10 = 40
4 x 6 = 24
Step 3. Add each product to get the answer:
20 x 10 = 200
20 x 6 = 120
4 x 10 = 40
4 x 6 = 24
Total = 384

📝 Tips:
🔆To break harder multiplication problems into easier ones, look for ways to multiply by numbers with a 0 at the end or by reducing other numbers to easier multiples.
🔅For example, to calculate 35 x 8, you can break it into any of the following:
▪️ 30 x 8 + 5 x 8 = 240 + 40 = 280
▪️ 35 x 2 x 2 x 2 = 70 x 2 x 2 = 140 x 2 = 280
▪️ 20 x 8 + 10 x 8 + 5 x 8 = 160 + 80 + 40 = 280
▪️ 10 x 8 + 10 x 8 + 10 x 8 + 5 x 8 = 80 + 80 + 80 + 40 = 280
☑️ We will return to this exercise to work through other multiplication problems.
