Negative and Positive Math

Introduction:

Negative and positive signs are the important concepts in mathematics.  In mathematics addition and subtraction and multiplication and division are the important basic arithmetic operations. Subtraction is represented as the symbol ‘-‘and addition is represented as the symbol ‘+’. In this topic we have to discuss about the negative and positive signs of math.

The Basic operations in math are

Positive (+)
Negative (-)
Multiplication (x)
Division (/)

Brief Description of Negative operation in math


Negative Operation:

Negative operation is ‘-’. It is used to subtract two or values.

For Example Subtract (5, 3) means 5-3 =8.

The most common key words used to represent subtraction are

Subtract
Difference
Minus
Negative
Less
Left
Example Problem:

Subtract 34-18

Solution:

Here the following steps to be followed,

Step 1: These are the two digit numbers.

Step 2: First we can subtract the unit digits.

Step 3: here the unit digits are 4 and 8

Step 4: 8 is greater than 4

Step 5: So we are not able to subtract directly.

Step 6: Borrow one from the ten’s digit value 3

Step 7: Now the tern’s digit value be 2

Step 8: one’s digit value be 14

Step 9: now 8 is subtracted from 14 that is 6

Step 10: therefore the unit digit is 6

Step 11: ten’s digit subtraction values are 2 and 1

Step 12: Therefore the ten’s unit digit be 1

Step 13: Therefore the difference of 34 and 18 is 16.



Brief Description of Positive operation in math


Positive Operation:

Positive operation is ‘+’. It is used to add two or values.

For Example Add (5, 3) means 5+3 =8.

The most common keywords used to represent addition are

Sum
Add
Plus
Increase
Increment
Total
Positive
More
Example Problem:

Find the sum of 15, 18.

Solution:

Here the following steps to be followed,

Step 1: These are the two digit numbers.

Step 2: First we can add the unit digits.

Step 3: The sum of the unit digits be 5 + 8 is 13.

Step 4: Then keep 3 and keep 1 as remainder to the next two digit term.

Step 5: Then the sum of ten’s digit number is 1 + 1 =2

Step 6: We can add this 2 to the remainder value 1

Step 7: Therefore the ten’s place value is 3

Step 8: And then unit place value is 3

Step 9: So the total sum of 15 + 18 be equal to 33.
