Okay here
1. Work from left to right but multiply before you add so it's
14-(4x3)-2 = 14-(12)-2 = (14-12)-2 = (2)-2 = 0 ans 0
2. With binary work from left to right. First digit is means 0 zero or 1 one. Second digit equal 0 zero or 1 two. Third digit means 0 zero or 1 four and so on. It goes 1,2,4,8,16,32,64.
so 1 1 1 1 1 = 31 or
16+8+4+2+1 = 31
3.
1 0 1 1 1 1 0=62 or,
32+0+16+8+4+2+0=62
4.
9= 8+0+0+1 or,
9= 1 0 0 1
5.
28= 16+8+4+0+0 or,
28= 1 1 1 0 0
6.
50= 32+16+0+0+2+0 or,
50= 1 1 0 0 1 0
7.
1 1 0 0 1 0 1= 101
64+32+0+0+4+0+1= 101
Hope this helps

Binary numbers are simple if your computer have a calculator, just bring it up and click on view, then switch it to scientific. There will be four modes: Hex, Dec, Oct, and Bin.
11111 is a binary number, make sure the bin mode is checked, put in the number and then click on the dec mode for the answer.
9,28, and 50 are decimal numbers, same method but backwards. make sure the dec mode is clicked on, put in the number and click on the binary number. It is pretty simple once you get the hang of it

the 1st one is 0 if you multiply the 4 x 3, subtract that by 14 and then 2.
and what are you supposed to do with the rest of them??? they are just numbers.

When doing these types of problems always remember "Please Excuse My Dear Aunt Sally" tells you the order of operation: Please (parenthesis) 1st if any Excuse (exponents 2nd if any) My (multiplication 3rd if any) Dear (division 4th if any) Aunt (addition 5th if any) Sally is (subtraction 6th step) multiply first 4x3 is 12 so 14-12-2= then subtract 14-12=2 2-2=0
For the rest I don't understand what you are supposed to do. But please remember the saying "please excuse my dear aunt sally" will always help you with long problems.
