Map Data

Description This is to learn binary - first you switch the switches at the top and above should be displayed the sum(sorry its not very clear when you enter in a 2) you then follow the map round and when you get to th BOTTOM LEFT you should see an answer in binary(above the b arrow) then when you get to an exit it displays the answer in decimal.

I know this could be made by using up only about a quarter of the map ( by combining the NOT and AND or OR gates or using inverting AND gates for the X-OR gate - those of you who know what im talking about will know what im talking about - in fact i am making a 4 bit adder using that method but it looks a bit boring cos almost all the gates are inverting AND gates and a few OR gates)

This map was inspired by alliedenvy's, whos although i like i did not think worked like a normal adder as it used a method of common factors, which although was extremely impressive it produced the numbers as you went along.

My method was for it to do the sum then produce the number as a full thing rather than doors one at a time.

For ease of understanding all the gates a separate and are separated by one piece of gold.

This map is totally uncheatable, anyone that can cheat it will get two DEDs

May i point out that allied envys x-or gate is wrong - i thought about doing a wee series on logic gates.

And i must say i love all of allied envys logic gate type maps all are 5/5 check them out.

last of all i thought about dedicating this map to B-MAN as is love for mathematics is almost unhealthy, but then i decided not to - no hard feelings B-MAN.

its easier if you just think that decimal (base 10) has columns like ones, tens, hundreds...

100s | 10s | 1s
| |
or

10^2 | 10^1 | 10^0
| |
binary is the same but with 2 instead of 10

2^2 | 2^1 | 2^0
| |

base 10 uses 10 digits(0-9)

but...

i already know binary...its so easy...

make hexidecimal level...now that would be crazy...
title is a slight pun 100 is 4 in binary so it would read:
binary 4 beginers or
binary for beginers

.::simple tutorial::.

binary is the way that computers work

instead of digits which can go from 0 - 9
binary only uses to 'digits' 0 and 1 (off or on)

to represent digits the computer encodes it by powrs of 2

so

2^0 = 1
2^1 = 2
2^2 = 4
2^3 = 8
2^4 = 16
2^5 = 32
and so on...

binary is always written from right -> left

here is a table of 3-bit binary(3-bit cos there is 3 from 2^0 -> 2^2)
4 | 2 | 1 | decimal
-------------------
0 | 0 | 0 | 0
0 | 0 | 1 | 1
0 | 1 | 0 | 2
0 | 1 | 1 | 3
1 | 0 | 0 | 4
1 | 0 | 1 | 5
1 | 1 | 0 | 6
1 | 1 | 1 | 7

so by adding the numbers of which there is an input of one underneath we can make any decimal number( in this case up to 7)

you can go bigger than 3 bit as well here is a few for you to try

1) 11
2) 1010
3) 1000
4) 0010
5) 1111101
6) 1011101010

answers

1) 3
2) 10
3) 8
4) 2
5) 125
6) 746

adding is similair

01 + 01 = 10 cos 1 + 1 = 2

111 + 101 = 1100 cos 7 + 5 = 12

hope that helped

if you still dont get it just ask and ill explain it mork







okay

my map is slightly cheatable if you go through the one ways the wrong way, but i must point out that is not my fault it is metanets or whoever made N - we should just all start calling them "both ways" instead of "one ways"

also you dont gain anythingfrom cheating it it is just a test level

Here

The right demo. Even though I don't quite understand, I think 00+00 should equal to 0.

Oops

Wrong demo
What this stuff is, but I think I have cheated your map.
Demo Data

yeah

but mine is different as it uses distinct gates - more like how a computer would work
