Simplify this solution Bonus Knowledge
Let’s dive into solving this expression step-by-step! First, we simplify the operations inside the parentheses: \( 8 + 2 = 10 \) and \( 4 - 1 = 3 \). Now plugging these back into the expression, we have \( 3(10) - 5(3) \). Next, we multiply: \( 3 \times 10 = 30 \) and \( 5 \times 3 = 15 \). Finally, we can subtract: \( 30 - 15 = 15 \). So, the value of the expression is \( 15 \)! 🎉 Understanding the order of operations is crucial—remember PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Missteps often happen when people rush through, so take your time to follow each step carefully!
