Beyond the Answer

Did you know that multiplying numbers can often be simplified by rearranging them? For instance, in your equation, you can do the multiplication inside the parentheses first: \( 10 \times 4 = 40 \). Then, you simply multiply that result by 8 to get \( 8 \times 40 = 320 \). Here's a fun tip for mental math: when multiplying by 10, simply add a zero to the number! So, \( 8 \times 10 \) is just \( 80 \), and when you add those extra zeroes (for \( 8 \times 40 \)), it becomes \( 320 \) super quickly! Keep practicing those tricks, and you'll be a math whiz in no time!
