How can I set the numbering of equation starting from a number larger than 1?

For example, I want the numbering of equations to start from “(2)”. Is it possible?

Yes you can.

You can set specific counters, in this case equation, using the counter function.

// enable numbering
#set math.equation(numbering: "(1)")

// set the counter for equations
// 1 indicates there is already 1 equation so the next use of an equation will selfupdate to 2.
#counter(math.equation).update(1)

You don’t need the context in front of the counter update.

Hi @jbirnick,

you are right that #counter(math.equation).update(1) does not need context.

I was confused because the #context counter(math.equation).get() does need context.
