For 11 to 20, use the distributive prope 11. \( 2(8+10)= \)

When you use the distributive property, you can break it down like this: \( 2(8+10) = 2 \times 8 + 2 \times 10 \). So, that gives you \( 16 + 20 = 36 \). Fun fact: you can apply this property to simplify calculations–it's like having a math magic trick up your sleeve! Let’s take another example: suppose you wanted to solve \( 3(4+5) \). If you distribute, it becomes \( 3 \times 4 + 3 \times 5 = 12 + 15 = 27 \). It's a nifty way to tackle tricky problems and ensures you get the right answer without ever breaking a sweat!
