Question

(68:4+13):6+((85-28):3+72(6*3)-11)*18-189=

Answer 1

1)68:4=17

2)17+13=30

3)30:6=5

 

4)85-28=57

5)57:3=19

6)6*3=18

7)72*18=1296

8)19+1296=1315

9)1315-11=1304

10)1304*18=23472

 

11)5+23472=23477

12)23477-189=23288

Answer 2

(68:4+13):6+((85-28):3+72(6*3)-11)*18-189=(17+13):6+(57:3+72*18-11)*18-189=

=30:6+(19+1296-11)*18-189=5+1304*18-189=5+23472-189=23288

Answer 3

Let's break it down step by step:

1. $68 + \frac{4}{13}$
2. Divide the result by 6: $\left(68 + \frac{4}{13}\right) \div 6$
3. $85 - 28$
4. Divide the result by 3: $\left(85 - 28\right) \div 3$
5. $6 \times 3$
6. $72 \times \left(6 \times 3\right)$
7. Subtract 11: $72 \times \left(6 \times 3\right) - 11$
8. Multiply by 18: $\left(72 \times \left(6 \times 3\right) - 11\right) \times 18$
9. Subtract 189: $\left(\left(72 \times \left(6 \times 3\right) - 11\right) \times 18\right) - 189$

Now, we can calculate this expression to find the result.
