TechTip: Math... Yum!

Now and again you might find yourself needing to modify a parameter JUST SO. Perhaps an art director has asked you to 'please move that logo down precisely 115 pixels, and move it 91 pixels to the right. Maybe it's already at 232/ 54, your brain hurts because you've got a perfectionist hanging over your shoulder, and you just can't add the numbers up in your head.

Don't reach for the calculator, let AE do the work. With a layer selected hit the 'P' key to bring up the position parameter. Assuming it's a 2d layer, you'll see two numbers (in the above case, 232 for the x axis position and 54 for the y axis position). Click once on "232" and (as expected) it'll become highlighted and will allow you to type in your changes. Now go to the END of the number and simply type "+115" (without the quotes). It should now say "232+115". Hit 'enter', et voila! AE will do the math for you.

This technique works with simple addition, subtraction, multiplication and division, but does NOT, alas, work for more complicated math. For instance, it won't calculate "232+5*(4/2)". Which, I'm sure, you do often.
