2 2 OP_ADD 3 3 op_mul OP_ADD

[Alko89]

You added 2 + 2 instead of multiplying them

[Altcoinproof]

My result is:

• 2 2 OP_MUL 3 3 OP_MUL OP_ADD

[dcota]

2 2 OP_MUL 3 3 OP_MUL OP_ADD

2 x 2 + 3 x 3 = 13 in stack

2 2 OP_MUL 3 3 OP_MUL OP_ADD

[javier_ortiz_mir]

2 2 OP_MUL
3 3 OP_MUL
OP_ADD

this is how i did it and it worked (i used 3 lines of code) … then I checked if it can be done in one line and it actually works the same way

2 2 OP_MUL 3 3 OP_MUL OP_ADD

Assignment Answer:
2 2 OP_MUL 3 3 OP_MUL OP_ADD

[VanellaVader]

I did 2 2 OP_MUL 3 3 OP_MUL OP_ADD on the first try, returned 0xD which I assume is 13

[R.C]

0xD its 10? D=10??? -------------------------

Maybe you want to learn about the hexadecimals to understand why 0xD is 13.

2 2 OPP_MUL 3 3 OP_MUL OP_Add

[Lyndon]

**1.) in order to get 0xD:

2 2 op_mul
3 3 op_mul
op_add

Welcome to the discussion about this section. Here you can ask questions or post feedback about this specific lecture.

Here the little homework.

[Alko89]

You could remove the OP_NOP commands, they are basically just null operations that don’t do anything but make the code messy

[markyb]

2 2 op_mul 3 3 op_mul op_add

this outputs 0xd (13)

would it be better practice to use:

3 3 op_mul 2 2 op_mul op_add

[markyb]

As the ‘9’ would be ‘a’ and the ‘4’ would be ‘b’
