5 4 3 2 1 =50
5*(4+3*2/1)=50
Is it necessary to use all the symbols?
I didn't use -.
5(4+3+2+1} = 50
Well, it seems like you're having fun with some math puzzles! You don't necessarily have to use all the symbols to make the equation work. In your first equation, you used multiplication, addition, division, and parentheses to get to 50. But in your second equation, you used only multiplication and addition. So, it's all about how creatively you can come up with different equations to reach the desired outcome. Keep on puzzling!
To evaluate the expression 5 4 3 2 1 = 50, you can use the given numbers and mathematical symbols (+, -, *, /).
One way to solve it step-by-step is as follows:
1. Start with the numbers: 5 4 3 2 1.
2. Use the multiplication (*) symbol to multiply 5 by the result of the expression inside the parentheses.
5 * (4 + 3 * 2 / 1)
3. Simplify the expression inside the parentheses.
5 * (4 + 6 / 1)
5 * (4 + 6)
4. Perform the addition inside the parentheses.
5 * (10)
5. Use the multiplication (*) symbol to multiply 5 by 10.
5 * 10
6. Evaluate the multiplication.
50
So, the expression 5 4 3 2 1 equals 50 using the given symbols.
To solve the equation 5 4 3 2 1 = 50, it seems like you are looking for a combination of mathematical operations using the numbers 5, 4, 3, 2, and 1 that would result in 50. Let's break down your attempts:
1. 5*(4+3*2/1)=50
In this attempt, you correctly used the multiplication symbol (*) to multiply 5 by the result of the inner expression (4+3*2/1). By following the order of operations (PEMDAS/BODMAS), you first multiply (3*2) to get 6, and then divide the result by 1, which remains unchanged. You then add 4 to the result to get 10. Finally, you multiply 5 by 10 to get 50. So, this expression is a valid equation that results in 50.
2. 5(4+3+2+1) = 50
In this attempt, you omitted the multiplication symbol (*) between 5 and the parentheses. Without the multiplication symbol, the equation would be interpreted as addition only. In this case, you would be simply summing up the numbers inside the parentheses: 4+3+2+1 = 10. Then, when you multiply 5 by 10, you get 50. So, this expression is also a valid equation that results in 50.
To answer your question, it is not necessary to use all the symbols in a mathematical equation. The symbols such as +, -, *, and / represent specific operations, and you can freely use or omit them based on the desired calculation. However, it's important to use the symbols correctly to achieve the intended result. Remember to apply the order of operations (PEMDAS/BODMAS) when simplifying mathematical expressions to get the correct answer.
