What is 8+3X6-4-1=13 using () only?? We have tried everything!
To solve this equation using only parentheses, you can rearrange the terms and introduce parentheses to control the order of operations (BIDMAS/BODMAS). Here's how you can do it step by step:
1. Start by multiplying 3 by 6: 3 x 6 = 18
Equation becomes: 8 + 18 - 4 - 1 = 13
2. Next, add the numbers inside parentheses: 8 + (18) - 4 - 1 = 13
3. Now, perform the addition: 8 + 18 = 26
Equation becomes: 26 - 4 - 1 = 13
4. Finally, perform the subtraction: 26 - 4 - 1 = 21 - 1 = 20
Therefore, by introducing parentheses to control the order of operations, the equation 8 + 3 x 6 - 4 - 1 can be written as (8 + (3 x 6)) - 4 - 1 = 20.
