ii. \( 6(1+4) \)

Did you know that parentheses play a super important role in the order of operations? They tell you to do what's inside them first, so in this case, you'd solve \(1 + 4\) to get \(5\) before multiplying by \(6\). This little trick ensures everyone gets the same answer, which is a huge deal in math! Now, let’s talk about how you might use this in real life! When you're calculating the total cost of items, you might use parentheses to make sure you correctly add up various groups of items before multiplying by tax or discounts. So if you have \(6\) t-shirts at a price of \(1 + 4\) (say $5), you'd calculate how much that would cost before adding any taxes or discounts. Pretty handy, right?
