# Need \prod to look like \Pi? [closed]

Occasionally I found $\prod$ (\prod) looked like $\sqcap$ (\sqcap). However if memory serves me right, is it more closer to $\Pi$ (\Pi) in many other places? What's more, since \sum is close to \Sigma, \Pi seems more suitable for \prod.

Note that the question is not 'Should \prod be replaced by \Pi?' but 'Should the feature of \prod be similar to \Pi?' That is, since \prod in many other places(such as books we usually read) looks like $\Pi$, whereas looks like $\sqcap$ in here, so I think someone who does not familiar with this kind font will easily get misunderstand.

This diagram illustrates the problem, even some other users cannot see it, but it is real a fact for me.

• Pro and con of \Sigma were discussed at length earlier: meta.math.stackexchange.com/questions/3932/… . – zyx Mar 22 '13 at 21:01
• In some fonts, pi looks like $\sqcap$. – Hurkyl Mar 23 '13 at 5:06
• Arial, for example, renders capital pi that way. – Hurkyl Mar 23 '13 at 5:17
• What is the question? – Antonio Vargas Mar 23 '13 at 7:45
• @AntonioVargas I have updated my post and then it is obviously. – Popopo Mar 23 '13 at 8:48
• @Hurkyl Is Math.SE using those fonts? – Popopo Mar 23 '13 at 9:06
• Seems to be a local problem on your machine. Did you restart your browser and did you try clearing its cache? In Opera the option to clear the cache is available under either Settings > Preferences > Advanced > History > Click on "Empty Now" or (more brutally) Settings > Delete Private Data. If you right click on a formula and choose Math Settings > Math Renderer which one is selected? Does the problem remain if you select another one? – Martin Mar 23 '13 at 20:57
• Thank you. I have emptied my browser but unfortunately the problem remains. However, I spotted the math render is set at HTML-CSS and the feature changed to bigger $\Pi$ after be set to MathML. So it seems a bit different from pdf files – Popopo Mar 24 '13 at 1:50

For me, \prod $\prod$ does look like \Pi $\Pi$. Except bigger. If it does not look that way for you, then maybe it is a problem with your browser, or the fonts on your computer. Why not tell us what they are?
• Well, \prod in many other places(such as books we usually read) looks like $\Pi$, whereas looks like $\sqcap$ in here, so I think someone who does not familiar with this kind font will easily get misunderstand . – Popopo Mar 23 '13 at 15:57
