Subtraction Tables 11 to 20
Subtraction tables are structured representations of the differences between two numbers. They help students refer to and learn subtraction without having to subtract the numbers manually.
What is Subtraction Tables 11 - 20?
The subtraction table from 11 to 20 shows the difference of all numbers within this range. The table is made of rows and columns, where the first row and column consist of all numbers from 11 to 20. The intersecting cells contain their differences. This table helps students visually learn the differences between all numbers from 11 to 20.
Subtraction Chart 11 to 20
When we need a quick reference for the result of any two numbers between 11 and 20 being subtracted, we refer to the subtraction chart. The first row contains the subtrahend, and the first column has all the minuend numbers.
For example, to see the result for 15 - 13, we check the cell formed by the 15th row and 13th column intersecting, and the result is 2. So, 15 - 13 = 2.
Writing Subtraction Table Chart
Follow these steps to write a subtraction table:
Step 1: Draw a grid based on the range of numbers. Here we take the numbers 11 - 20.
Step 2: The first row represents the minuend.
Step 3: The first column contains the subtrahend.
Step 4: Subtract the numbers and fill each intersectional cell.
Reading Subtraction Table Chart
Let’s take an example to understand how to read a subtraction table. To find 19 - 14 using a subtracting table, we look for the 19th row as 19 is the minuend. Then we look for the 5th column because 5 is the subtrahend.
Now, we trace the cell where the row and column intersect on the table, which gives us the final answer. So, according to the subtraction table 11 - 20, 19 - 14 = 5.
Tips and Tricks for Subtraction Tables 11 to 20
Subtraction tables make calculations easier for students, and these tips and tricks help them be more efficient.
Tip 1: Remember that any number subtracted by itself gives 0. For instance, 16 - 16 = 0.
Tip 2: If the number in the column is greater than the number in the row, the answer will be negative. For example, 13 - 18 = -5.
Tip 3: Learn column patterns for easily making the table. For example, the difference within each column increases by 1 as you move down.
Common Mistakes and How To Avoid Them in Subtraction Tables 11 to 20
Here is a list of some mistakes students often make while making or reading the subtraction table 11 - 20, with ways to avoid them.
Mistake 1
Misreading the rows and columns
Students get confused and reverse the order of subtraction, resulting in wrong answers. Remember that row number (minuend) - column number (subtrahend) gives the correct answer.
Mistake 2
Assuming positive answers
Students think that the answer cannot be negative. This is incorrect; if the subtrahend is bigger than the minuend, then the answer will be negative.
Mistake 3
Forgetting about the zero rule.
Any number that is subtracted from itself gives the number zero; do not look for a different answer.
Mistake 4
Not verifying using addition
It is wise for students to check the table after making it using addition. For instance, if 17 - 12 = 5, then 5 + 12 = 17 confirms that the subtraction was correct.
Mistake 5
Ignoring patterns
Individually learning each and every result becomes hard for students. An easier way of learning the table is by identifying patterns within the table. Each row decreases by 1 across, and each column increases by 1 as it moves downwards.
