A definition of number line is placed in the correct position of numbers. The number line is generally represented the positive and negative numbers. Number line is commonly performing by the addition and subtraction operation. The general format of the line number is {-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5}. Next we discuss about this articles open number line.
Open Number Line
The open number line is defined the empty line used in the operations are addition and subtraction. Open number line is generally used in the three parts. Those parts are organ of open line number, positive value of open line number and negative open line number.
The positive value means larges values of the open line number it is represented the 25, 35 and etc.
The negative line number means smallest values of the open line number it is represented the -50, -75 and etc.Understanding how to solve matrices is always challenging for me but thanks to all math help websites to help me out.
Example Problem of Open Number Line
Problem 1:
Calculate the following numbers using open line numbers.
(77 + 2 + 8 + 3)
Solution
The number is 77 + 2 + 8 + 3
The above all numbers are positive number. So that numbers are move from the open line number is right side only.
Step 1: Move 2 units from right side of the open line number. The answer is 79.
Step 2: Move 8 units from right side, the answer is 87
Step 3: Move 3 units from right side, the answer is 90.
The answer of the 77 + 2 + 8 + 3 is 90.
Problem 2:
Calculate the following numbers using open line numbers.
(63 + 12 - 3)
Solution
The number is 63 + 12 - 3
The above numbers are positive and negative number. So positive numbers are move from the right side and negative number are move from left side of the open line number.
Step 1: Move 12 units from right side of the open line number. The answer is 75.
Step 2: Move 3 units from left side, the answer is 72
The answer of the 63 + 12 - 3 is 72.
