# For all math symbol [closed]

How to use for all math symbol for equation like this in LaTeX "for j = 1...J and t = 1...T"?

$$\label{Con2} \sum_{k=1}^K\sum_{\tau=1}^t q_{jk\tau} \leq BF_{jt} \cdot \sum_{\tau=1}^t w_{j\tau} \qquad \forall j \textrm{for}\quad j=1,\ldots,J \quad \textrm{and} \quad t=1,\ldots,T$$

• Can you clarify your question? What's the problem? Nov 30, 2020 at 21:32
• Are you asking about \forall? Nov 30, 2020 at 21:37
• Maybe you should try detexify.kirelabs.org/classify.html

• try j \in \integer from china2e package. Dec 1, 2020 at 0:31

Using \forall and making a slight change one option is seen by:

\documentclass[12pt]{article}
\usepackage{amsmath}

$$\sum_{k=1}^K\sum_{\tau=1}^t q_{jk\tau} \leq BF_{jt} \cdot \sum_{\tau=1}^t w_{j\tau} \qquad \forall \quad 1 \leq j \leq J \quad \textrm{and} \quad 1 \leq t \leq T$$

\end{document}


which produces

• Thank you for the response but if i want something like \forall j and \forall k. How to write where j and k not starting from 1 but from 2 or not end at J but something else. Dec 1, 2020 at 22:12
• @macscm Depending on what the something else is then to format would be changed. For example it could be \forall j, k \in \mathbb{N}_0 with use of \usepackage{amssymb}. Many other examples exist. Dec 2, 2020 at 5:35
