Can You Solve this Math Puzzle? Equate -9²+81=? Solution
This math puzzle is quite challenging, and we invite you to give it a try and find the answer.
A viral math problem on Instagram has stirred up a lot of debate, with over 6 million views. The question involves a negative sign, followed by 9 squared plus 81, leading to a disagreement between those who think the answer is 162 and those who argue it's 0. However, the correct answer is indeed 0.
To remember these rules, we use acronyms like PEMDAS or BODMAS, which stand for Parentheses/Brackets, Exponents/Orders, Multiplication and Division, and Addition and Subtraction. When you have two operators with the same priority, you calculate from left to right. In this expression, we first compute the exponent, giving us 9 squared, which equals 81. Then we add the opposite of 81 to 81, resulting in 0, and that's the correct answer.
It's worth noting that there's a common misunderstanding about this concept, even among prospective elementary teachers. This understanding is crucial because it has implications in various mathematical contexts, from graphing functions to higher-level mathematics like the standard normal curve. So, zero is indeed the correct answer!
Calculate the Result of 120 ÷ 10 + 5 x 2 - 15 ÷ 3=?
To find the solution, apply the order of operations. Start with the divisions and multiplications from left to right: 120 ÷ 10 equals 12, and 15 ÷ 3 equals 5. Now the equation becomes 12 + 5 x 2 - 5. Next, perform the multiplications and additions/subtractions from left to right: 5 x 2 equals 10, and 12 + 10 equals 22. Thus, the solution is 22.
Determine the Value of 180 ÷ 9 + 7 x 3 - 18 ÷ 6=?
Follow the order of operations as usual. Begin with the divisions and multiplications from left to right: 180 ÷ 9 equals 20, and 18 ÷ 6 equals 3. Now the equation becomes 20 + 7 x 3 - 3. Next, perform the multiplications and additions/subtractions from left to right: 7 x 3 equals 21, and 20 + 21 equals 41. Therefore, the solution is 41.
