# How To Solve Math Problems Fast

As you are placing your order a soccer team of 26 players enter and five guests leave. You and your friend make 2 people 26 soccer players= 28 guests 28 guests - 5 that leave= 23 guests left.

You can solve this problem using subtraction first like this: 26 soccer players - 5 that leave= 21 guests 21 guests 2 people (you and your friend)= 23 guests The answer is the same no matter which operation you use first to solve the problem.

, or If I eat four slices of pizza tonight, will I have enough for lunch tomorrow?

Using mental math to solve two-step word problems can be easy and very useful in everyday life, and you might not even know it.

At the counter you and your friend decide to order a pizza and soda. A small has six slices, a medium has eight, and a large has ten.

The two of you both want four slices of pizza to eat.Four thousand years ago, the Babylonians invented multiplication. On March 18, two researchers described the fastest method ever discovered for multiplying two very large numbers.The paper marks the culmination of a long-running search to find the most efficient procedure for performing one of the most basic operations in math.If you’re multiplying two two-digit numbers, you end up performing four smaller multiplications to produce a final product.The grade school or “carrying” method requires about is the number of digits of each of the numbers you’re multiplying.40 ounces of soda / 2 people (you and your friend)= 20 ounces of soda each You can also do the inverse operation for each of these problems: 8 slices of pizza / 2 people= 4 slices of pizza each 20 ounces of soda x 2 people= 40 ounces of soda altogether After your meal, you both decide to fill up the car with gas before hitting the road.Gas costs .00 per gallon and the car tank can hold 14 gallons. We solve this problem as follows: .00 per gallon x 14 gallons= to fill the car up with gas for gas / 2 people (you and your friend)= you each have to pay for gas The inverse for getting gas would be as follows: to fill up the car / 14 gallons= per gallon to pay for gas x 2 people= in total Using mental math to solve word problems allows you to solve problems quickly.“If you want to know how fast computers can solve certain mathematical problems, then integer multiplication pops up as some kind of basic building brick with respect to which you can express those kinds of speeds.” Most everyone learns to multiply the same way.We stack two numbers, multiply every digit in the bottom number by every digit in the top number, and do addition at the end.Van der Hoeven describes their result as setting a kind of mathematical speed limit for how fast many other kinds of problems can be solved.“In physics you have important constants like the speed of light which allow you to describe all kinds of phenomena,” van der Hoeven said.
