You could do this using Javascript.1) create a textfield2) create a submit button3) define two Javascript variables: a running tally, and a click-counter4) give the button an onclick event that calls a function that works like this:read the value from the text fieldconvert it to a numeric valueif that value is 0 {if the counter != 0 {display the tally and the average (which equals tally over counter)}else{either display an error message, or 0 as both the tally and average - to your taste.}reset both the tally and the counter to 0}else{add the value to the tallyincrement the counter by 1}And here's a working example of how to do it:span.buttonClass{background-color: #C8C8C8;padding: 4px;border-width: 2px;border-style: outset;font-weight: bold;}The Summinator!var tally = 0, counter = 0;function addValue(){var textfield = document.getElementById("addVal");var avgfield = document.getElementById("avgfield");var sumfield = document.getElementById("sumfield");var num = parseFloat(textfield.value);var sum, avg;textfield.value = '';if(isNaN(num)){ // make sure they entered a numberalert("Please enter a numeric value.");}else{if(num != 0){tally += num;counter ++;sumfield.textContent = "";avgfield.textContent = "";}else{if(counter == 0){sum = avg = 0;}else{sum = tally;avg = tally / counter;}sumfield.innerHTML = "The sum is " + sum;avgfield.innerHTML = "The average is " + avg;tally = counter = 0;}}}Add ValueYou can even make it a little nicer by having it output the sum and average each time a number is entered, rather than waiting for the zero input (which would still reset things). That actually simplifies the code too, and would look like this:...if(isNaN(num)){ // make sure they entered a numberalert("Please enter a numeric value.");}else{if(num != 0){tally += num;counter ++;sum = tally;avg = tally / counter;}else{sum = avg = tally = counter = 0;}sumfield.innerHTML = "The sum is " + sum;avgfield.innerHTML = "The average is " + avg;}...
the number zero is first used by Indians only not by any one else<br /><br /><br /><br /> The number zero was actually invented by the <i><b>Ancient Egyptians
It is 81*81*81. Which is 531,441.
9² = 9 × 9 = 81
The natural abundance of Br-81 is approximately 49.31%.
The isotope 79-Br is more common than 81-Br because it is the most stable isotope of bromine. 79-Br has a higher abundance in nature because it has a longer half-life compared to 81-Br, which is less stable and less abundant.
The correct nuclide symbol for bromine-81 is ^(81)Br.
The most common isotope of bromine is bromine-79 (Br-79), which makes up about 51% of naturally occurring bromine.
To find the mass of Br-79, you subtract the difference in mass between Br-81 and Br-79 from the mass of Br-81. Mass of Br-81 = 80.9163 amu Mass of Br-79 = Mass of Br-81 - (Mass of Br-81 - Mass of Br-79) = 80.9163 - (80.9163 - 78.9183) = 78.9183 amu
Br-80 has 35 protons.
The element with the symbol Br is Bromine. Bromine has 35 protons and approximately 45 neutrons in its most common isotope.

The number of peaks in a mass spectrum depends on the complexity of the molecule being analyzed. A simple molecule may have one or a few peaks corresponding to different fragments formed during ionization, while a more complex molecule can produce multiple peaks due to different fragmentation patterns.
