\( 17\times 9=...............\times 17 \)

To solve for the unknown in the equation \( 17\times 9= x \times 17 \), you can divide both sides by 17 (since 17 is not zero) to isolate x. This gives you: \[ x = 9 \] So, \( 17\times 9=9\times 17 \), reflecting the commutative property of multiplication that states you can multiply numbers in any order and get the same result. Now, let's think about multiplication! It’s not just a tedious task at school; it’s the heartbeat of many real-life situations! From calculating expenses at the grocery store to figuring out time taken for trips based on speed, multiplication pops up everywhere you look, making life a whole lot easier. And if you want to sharpen your multiplication skills, there are plenty of fun methods to try! For example, the "lattice method" provides a visual way to multiply digits, while "finger multiplication" can impress friends when calculating products up to 9. Keep practicing, and you'll become a multiplication master in no time!
