It's not so easy DSLR it's a bit more advanced DSLR Look in the user's manual, but if you will have a automatic program (you will have "P" in the right top corner, like on the site 18) it won't be so dificult to take a photo. When you learn the basic then you can try to discover next options
Check what kind of the lens you have, zoom or not, and what kind, you have all information write on it. For example (50mm 1:2.8) or (10-20mm 1:4-5.6) then you will know what kind of photos will go the best, for example for macro photos you need special lens, because normal lens you can not do photos from so close.
The memory card goes in on the right-hand side of the camera, there is a small lever on the rear with a 'Pac-Man' type image by it; flick this lever and the memory card door will open.
Check that the camera is in 'P' mode; if it isn't, press & hold the 'Mode' button on the top-right of the camera whilst rotating the rear command wheel until 'P' shows in the top LCD. Check that the camera's AF is set to 'S', this is selected by the small knob on the left side of the lens mount (near the camera's base). If you want to use the flash, press the button on the left side of the prism to pop it up. The AF selection mode is also a small lever on the rear, 'closest subject priority' using all AF points is (IIRC) the white rectangle.
Depending on what lens is fitted (it might be a prime so it won't zoom), the zoom is used by rotating a ring on the lens; this ring will have numbers on it (i.e. 18, 24, 35, etc).
The user manual that ~Svenler linked to should tell you anything else you need to know, but it might be daunting to read.
