This is a video of the numbers 0-9 being written in Hebrew.
Notice that the numbers 1, 7, and 9 may be written slightly differently than you're used to, unless you are German in which case this is the same style you're used to. 1 has a front tail, even touching the line sometimes, depending on who is writing. 7 has a line through it. And 9 is often written like a lowercase "g" that is above the line.
