hey do i have even + even + odd is it even or odd?

Even + Even + Odd = Odd. This is since Even + Even = Even, so it's the same as Even + Odd, which = Odd.

why do we do 2 step word problems

Sometimes a real-world problem can't be solved with a single operation.

How do i know if i'm right or wrong before i press the check button?

Checking your answer in math is a skill you develop as you improve your mathematical intuition (number sense). Here are some general ways to check an answer. 1. Check that your answer meets all the conditions in the word problem or equations. 2. Use the reverse operation to check arithmetic. Example: if you are doing the problem 86-47, check that your answer plus 47 equals 86. 3. Estimate to see if your answer has reasonable size, or if your answer is clearly too big or too small. 4. Find a second method of doing the problem. If you think hard enough, you will see that many math problems have more than one method. Check if you get the same answer you got before. Have a good day!

Arithmetic patterns and problem solving: FAQ

Google Classroom

Frequently asked questions about arithmetic patterns and problem solving.

What's the difference between a one-step and two-step word problem?

In a one-step word problem, we only need to perform one operation (like addition, subtraction, multiplication, or division) to find the answer. In a two-step word problem, we need to perform two operations

What is a $2$ ‍-step expression?

2

-step expression is a math problem that requires two steps to solve. For example,

3 x + 2 x

is a

2

-step expression. To solve it, we first add

3 x

and

2 x

together to get

5 x

, and then we can solve for

x

How do we use estimation in word problems?

In word problems, we can use estimation to help us check our work. For example, if we're trying to find out how many apples there are in

11

bags, each with

6

apples, we can estimate that there are about

60

apples. If we calculate the exact answer and get

15

, we know we've made a mistake.

What are patterns in arithmetic?

Patterns in arithmetic are sequences of numbers that follow a certain rule. For example, the sequence

2, 4, 6, 8, 10

is a pattern in arithmetic because we're adding

2

to each number to get the next one.

How do we use the topics from this lesson in the real world?

There are many ways we use arithmetic and problem solving in the real world! For example, we might use estimation to plan a budget, or we might use two-step word problems to figure out how much we need to save to buy something we want.
