Math round 5

In math class this round I’ve learned about algebra, negative number and integers, coordinate graphs, rate and last but not least, speed. Algebra is a type of math that we solve problems with number and letter, example: x + 2 = 8, find the value of x. Algebra is also mean to find the value of the letter. 

Negative numbers and integers, negative number is a number that less than 0 and it goes to the left of the line. Integers are the numbers that have the value more than -1 and it goes to the right of the line. 

Coordinate graph is a graph that we use to locate point. A number on the x-axis called an x-coordinate, and a number on the y-axis called a y-coordinate. 

Rate is a graph that shows the change of number. We use rate to see and to show how the value of thing change and some company use rate to see how the business go.

Speed is the distance that we traveled per unit of time. It tells how fast an object move.  The higher speed the faster it a thing move.
