The 7405 is a hex inverter with open collector-outputs, the I/O's is as follow:Input Inverted outputPin1=A1 Pin2=Y1Pin3=A2 Pin4=Y2Pin5=A3 Pin6=Y3Pin9=A4 Pin8=Y4Pin11=A5 Pin10=Y5Pin13=A6 Pin12=Y6Power pinsPin14=Vcc +Pin 7=GND
binary addition of two bits is called a half adder ,and of three bits is called a full adder to be more lucid in my explanation a half adder doesnot consider a carry generated from the previous added pair of binary numbers consider an example :- A=a1a2a3a4 + B=b1b2b3b4 = sum=s1s2s3s4 the actual addition procedure is a4 and b4 are added first then the sum is stored in s4 and the generated carry is added with a3 and b3 and the process continues so addition of a4 and b4 where there is no input carry is carried out by half adder and the addition of c1+a3+b3 is carried out by full adder. but practiclly the first situation a4+b4 can be considered as a4+b4+0 so all the addition can be performed by full adder it self truth table for both half adder A B s c 0 0 0 0 0 1 1 0 1 0 1 0 1 1 0 1 for full adder c1 A B s c 0 0 0 0 0 0 0 1 1 0 0 1 0 1 0 0 1 1 0 1 1 0 0 1 0 1 0 1 0 1 1 1 0 0 1 1 1 1 1 1 where s and c can be viewed as the sum and carry on solving the k-map for full adder and half adder we can obtain the fuctions of sum and carry

Put the hourly rate in cell A1 and the number of hours in cell A2. Put the following formula in cell A3 [=A1*A2]. You will see the total of Rate X Hours in cell A3.
=IF(A1+A2=A3,"True","False") As an example: put this LibreOffice Calc formula into A4. Type a number in A1 and also in A2, and type the answer to the sum in A3. If the answer in A3 is correct, then "True" will appear in A4 and, if wrong "False" will appear in A4.
You need to replace the break pads or you can bodge it up by connecting the two wires
You would use an IF function to do this. If you knew that A3 can only have yes or no in it, then in another cell you would put this:=IF(A3="yes",A1,A2)If it is possible that A3 might not have yes or no in it, then you would need to have a third action, like leave the cell blank or put zero into. In this case the formula would be:=IF(A3="yes",A1,IF(A3="no",A2,""))or=IF(A3="yes",A1,IF(A3="no",A2,0))Note that there are two brackets at the end because there are two IF functions. It would be safer to use one of the final two formulas, as if A3 was blank, you would get an error. You should also be careful to have the yes and no in the same case all the time, although Excel will say they are equal if it was like yes and YES.
Formulas are typed into a spreadsheet cell. For instance: type in cell A3 =SUM (A1+A2) and put a random number in A1 and in A2. The sum total will appear in A3.
Put them into cells. So if 1110 was in cell A3 and 674 was in cell B3, the formula could be: =A3 - B3
This question is not clear. You can display results in a cell if you put a formula in a cell. EXAMPLE: If you put =A1+A2 in cell A3, you will display the results of the equation in cell A3. If this does not answer your question, ask another question with more specific words.
There following two options should work:=sum(A1:A3) or=A1+A2+A3
Put the Audi a3 in a bown of rice or something that will soak up the water. Keep it in there for at least 2 days. My iPod shuffle got water damaged and was not working. I put it in some rice for about a day or so and it worked like new
