In one sentence, describe what the following article is about: For example, if you are multiplying 125 x 15, you can break this up into two component parts (factoring out, essentially). First, multiply 125 x 10 (1250). Second, divide that answer by 2 (625). Now add both numbers together (1250 + 625 = 1875).  Instead of dealing with writing down the multiplication and work right-to-left, you can realize that you’re looking for 125 x (10 + 5) = (125 x 10) + (125 x 5) = (125 x 10) + (125 x 10 / 2). By breaking the problem down to one simple calculation of 125 x 10, one division by 2, and one addition, you avoid a trickier multiplication. Always look for ways to use simpler calculations or memorized multiplication tables, for instance, to simplify a harder calculation. Understanding these component parts can then be applied to leaving a 15% tip, for example, and all you have to do is move some decimal places afterward. Practicing is the best way to keep your mind sharp when it comes to mathematical calculations. Work on different types of problems each day: word problems, percentage problems, long division, decimal calculations, etc.  Challenge yourself to work on areas that you notice you struggle in. If fractions tend to give you a hang up when calculating, spend a week or two just doing fraction calculations. Even just looking at multiplication tables or worked out problems is beneficial. Eventually, you will start to notice patterns and new ways to deconstruct problems you didn’t see before. Saying the numbers and process out loud will make you hear the calculation as you work it out, too. This adds a new layer of learning and memorizing on top of what’s already there. Hearing yourself say a number creates another mental copy of the number in your working memory. With an auditory and visual copy of the number, it becomes easier to recall as you’re calculating. Once you’ve done a calculation in your head, do it with pencil and paper. See if you have the same answer. Now, consult a calculator to check the answer once and for all.  Although fingers can be a quick way to hold a number aside during a calculation, try to rely on the visual memory or even auditory memory instead. Testing yourself by not relying on a calculator or even writing the numbers down will help with your working memory, number recall, and even visual/spatial skills.
Summary: Simplify calculations into smaller, easier calculations. Do a few small calculations at least once a day. Vocalize your mental process to yourself. Try to do as much in your head as possible.

Problem: Article: Most rear-facing seats consist of two parts: the base and the infant carrier. You will install the base, the part that remains in the car. Follow the manufacturer’s instructions for removing the carrier from the base. Usually, there is simply a lever or button to activate. Many car seat bases include an attached belt with two hooks that can latch onto designated spots near your car’s seat belt area. If your car manufacturer included these, snap the hooks onto the metal bars at those designated spots.  Tighten the anchor belt attached to the base until the base is snug against the seat. Check the manufacturer's instructions if you aren't sure if your car or seat has this option, or how to use it. There may also be a place to feed the car’s seat belt through the base for added security. If your car seat does not use the anchor system, it will be secured to the backseat with the car’s seat belt.  Feed the belt through designated openings in the base and buckle it. The seatbelt should fit cleanly, and not be twisted or bunched up.  Read the instructions to study where you are supposed to put the belt if you aren't sure. Every vehicle and seat is different, so it's important to get this right. Not latching the seat belt correctly can increase the risk of the child getting injured in an accident. Set it onto the base so that the child would face the rear. It should click when it's in the right position. You can then practice taking the carrier out (by activating the lever or button) and setting it back into get a feel for things. Rear facing car seats usually have bases that can rest at different angles. The youngest infants will need to be in the more reclined position. This helps them breathe properly.  Most infant carriers have level indicators. Once yours is in place, read this level to see if the seat is at the correct angle for the babies weight/height/age. Check the manufacturer’s instructions for how to properly read the level if it isn't clear. Change the base angle if the level is not correct or your child. Usually, this involves turning the base over and rotating a piece. Remember to change the angle later on (or switch to a different seat) if the baby outgrows one setting.
Summary:
Separate the carrier from the base. Anchor the base to your car's back seat. Thread the seat belt through the base, alternatively. Pop the infant carrier into the base. Double check the base angle.
