# Easy math problems

Put your ability with numbers and problem solving skills to the test with classic brain teasers that will leave you scratching your head in search of answers. How many of the brain bending questions can you answer correctly? Give them a try and find out! I am an odd number. A problem with one variable: How old is Al?

## Solved Examples

Many single-variable algebra word problems have to do with the relations between different people's ages. Al's father is He is 15 years older than twice Al's age.

We can begin by assigning a variable to what we're asked to find. We also know from the information given in the problem that 45 is 15 more than twice Al's age. How can we translate this from words into mathematical symbols? What is twice Al's age? That equals 45, right?

Now we have an equation in terms of one variable that we can solve for x: It's always a good idea to check our answer: Solving a problem using one or two variables: How old is Karen? We can solve this problem using either one or two variables: Karen is twice as old as Lori. Three years from now, the sum of their ages will be We'll let Lori's age be x.

We can set up a chart: If we want to use two variables to express the given information, we will need two equations to solve for these variables.

Start by assigning variables. We want to find Karen's age, so let's call that K. But we need a variable for Lori's age too, so we will call her age L. We know that Karen is twice as old as Lori. Another way of saying this is that Karen's age is 2 times Lori's age. This gives us our first equation:Sample Problems by Topic Arithmetic. 1. 3 + 5 In arithmetic, easy math problems would involve addition or subtraction (without any carrying or borrowing).
