Noções básicas de planilhas
Seis unidades sobre como uma planilha funciona no Microsoft Excel e no Google Sheets: células e intervalos, os tipos de valor que uma célula pode guardar, como escrever fórmulas, somar com SUM, copiar fórmulas para que elas se ajustem sozinhas e ler os valores de erro. Cada unidade tem uma pequena planilha que funciona de verdade, com tarefas conferidas enquanto você digita.
