What's the answer to this math problem?

Question

2 + 3[4 + 5(6 +7[8 +9(10 + 11)])]

Answer 1

218790  

Answer 2

okay...

this is the same as saying (10+11) x (8+9) x (6+7) x (4+5) x (2+3)

which = 208 845

Answer 3

You work from the middle outward.

2 + 3[4 + 5(6 +7[8 +9(10 + 11)])]

Step one: 2 + 3[4 + 5(6 +7[8 +9(21)])]

Change 10+11 to 21

Step 2: 2 + 3[4 + 5(6 +7[17*21)])]

Change 8+9 to 17

Step 3: 2 + 3[4 + 5(6 +7)[357]

Multiply 17 and 21

Step 4: 2 + 3[4 + 5(13)[357]

Add 6+7

Step 5: 2 + 3[4 + 5(4641)]

Multiply 357 and 13

Step 6: 2 + 3[9(4641)]

Add 4 and 5

Step 7: 2 + 3(41769)

Multiply 9 and 4641

Step 8: 5(41769)

Add 2 and 3

Step 9: 208,845

Multiply 5 and 41769.

Answer 4

2 + 3[4 + 5(6 + 7[8 + 9(21)])]

2 + 3[4 + 5(6 + 7(8 + 189)])]

2 + 3[4 + 5(6 + 7(197)])]

2 + 3[4 + 5(6 + 1379)]

2 + 3[4 + 5(1385)]

2 + 3[4 + 6925)]

2 + 3[6929]

2 + 20787

20789

Answer 5

           2+3(4+5[6+7(8+9[10+11])])=

               2+3(4+5[6+7(8+9[21])])  =

               2+3(4+5[6+7(8+189)])   =

                 2+3(4+5[6+7(197)])     =

                   2+3(4+5[6+1379])     =

                       2+3(4+5[1385])     =

                            2+3(4+6925)    =

                               2+3(6929)     =

                               2+20787       =20789



                  

                        

  

                                      

Answer 6

you start with the inner-most parentheses which in this case would be (10+11). so we now have 2+3[4+5(6+7[8+9(21)])]. then we go to 4+5, which would be 2+3[9](6+7[8+9(21))]. So then we do (6+7), which would put us at 2+3[9](13)[8+9(21)]. Then we finally do 8+9 which would make the final equation be, 5[9](13)[17](21).  your answer is 208,245. hope i helped=]

Answer 7

u add 2+3=5

then add 4+5=9

then 6+7=13

then 8+9=17

then 10+11=21

then add 5+9+13+17+21=65

hope that helps!

Answer 8

first step we are going to add the 10+11

2 + 3[4 + 5(6 +7[8 +9(21)])]

Then we are going to multiply the 9 times the 21

2 + 3[4 + 5(6 +7[8 +189])]

Then we are going to add the 189+8

2 + 3[4 + 5(6 +7[197])]

Then we are going to multiply 7 times 198

2 + 3[4 + 5(6 +1379)]

Now lets add the 6+1386

2 + 3[4 + 5(1385)]

Multiply the 5 times the 1392

2 + 3[4 + 6960]

Now add 4 + 6925

2 + 3[6929]

Multiply the 3 times the 6964

2 + 20787

Now add the final 2

(The strategy is finding the innermost term and working your way out, the other answers that were given are wrong.)

Your answer is

20789

Answer 9
