Ola,

Preciso calcular o valor de duas variaveis emitidas por um formulario html. Como posso fazer isso? O PHP ou o HTML tem funcao de calcular valores, assim como o MySQL?

Grato pela ajuda

HTML não, mas PHP, sim.

Considerando que o formulário tem método POST:

$v1 = (int) $_POST['valor1'];
$v2 = (int) $_POST['valor2'];

echo $v1 + $v2;

Coloquei o (int) para ter certeza de que o valor usado na soma é inteiro, mas também pode-se usar o tipo double (ou float).
