@dull oyster What do you have so far

[dull oyster]

not a = IF(F, a, b) but im not sure

[wind pelican]

Well, try it and see

Fill in this truth table:

a  b  |  IF(F, a, b)
0  0  |  
0  1  |  
1  0  |  
1  1  |

[dull oyster]

0  0  |  0 
0  1  |  1
1  0  |  0
1  1  |  1

[wind pelican]

So is it correct?

[dull oyster]

no

[dull oyster]

IF(b,a,b) for a and b

[wind pelican]

Does the truth table work?

[wind pelican]

Do you want a hint?

[dull oyster]

yes

plz

[wind pelican]

Well, the function shouldn't depend on b at all

[dull oyster]

how come its a and b

[dull oyster]

IF(b,a,T)

[wind pelican]

It shouldn't have b in it anywhere

[dull oyster]

IF(T,a,F)

[wind pelican]

Draw a truth table for that

[dull oyster]

are u sure not IF(b,a,b)

[wind pelican]

You tell me

Write out a truth table

[dull oyster]

how do i know the values of IF(b,a,b) making the truth table tho?

a b | IF(b,a,b)
0 0 | 0
0 1 | 1
1 0 | 0
1 1 | 1

[wind pelican]

Does that truth table match what you should see for the function you're implementing?
