Select a region on the webpage to sum all numbers within it Ever find yourself using a calculator to quickly add numbers you see on a website? With Suminator all you have to do is click on the extension icon, then use a rectangle selector tool to select the numbers on your screen and it'll give you the sum and average of any of the numbers you select in the bottom right of the screen. It'll also copy the total or average to the clipboard. Simple, but sometimes very helpful. Keeps you from having to pull out another calculator and lets you work quickly without breaking your workflow. Suminator also keeps a history of the numbers you've calculated. Access history by right clicking on the extension icon. You can turn off history by right clicking the icon and going to settings.
