\( 5 \times 8=40 \), then \( 5 \times 4 \)

If \( 5 \times 8 = 40 \), then to find \( 5 \times 4 \), we can think of it this way: half of \( 5 \times 8 \) will give us \( 5 \times 4 \). Since \( 40 \) divided by \( 2 \) equals \( 20 \), we have \( 5 \times 4 = 20 \). So, there you go—simple as pie! Now, let's talk about multiplication's real-world application! Imagine you're at a bakery, and you want to buy 5 boxes of cookies, each containing 4 cookies. Instead of counting each cookie individually, you can use multiplication to quickly find out you’ll have \( 5 \times 4 = 20 \) delicious cookies to enjoy! Multiplication makes everyday shopping a breeze!
