Steps on how to subtract two digits numbers up to seven digits word problems
We have designed these captivating steps on how to subtract two digits numbers up to seven digits word problems to enhance kids' confidence and problem-solving skills.
As a matter of fact, we are encouraging kids to practice solving subtraction problems with these unique, short, and simple steps below. Here, you'll find motivating strategies helpful for quickly arriving at accurate answers.
Step 1: IDENTIFY THE PROBLEM:
To identify the problem, read the word problem properly, then highlight facts such as numbers, important keywords, and what the problem wants you to solve.
- That is to say that, when you come across subtraction word problems, some of the keywords you'll come across include:- less, minus, take away, left, decrease, difference, remain, change, how many more, how much more, subtract, fewer, deduct, etc.
Note: One key Element for learners to understand is that they should not always rely on keywords alone. That is to say; the same keyword can have different meanings in different word problems.
For this reason, we reiterate on the importance of reading the question very carefully to understand the situation that the word problem is describing, then figure out exactly which operation to use
Step 2: STRATEGIZE AND DETERMINE THE OPERATIONS:
Now, ask yourself, "how can I solve this problem?"
One essential fact you should remember is that each word problem may require a different format. Hence, the key points below will enable young math learners to tackle any format however it comes.
- First, the keyword in the word problem will help clarify the operation that you need to carry out
- However, it would be best not to rely totally on keywords; also, try to understand the problem's situation.
Step 3: SET UP A NUMBER SENTENCE AND AN EQUATION:
- Now, after determining the operation you need to perform, form short phrases to represent the given word problem. This visual representation of the most vital information makes it easier to solve the word problem.
- Then, write down a numerical equation representing the information given in the word problem.
Step 4: SOLVE THE PROBLEM:
Now, after writing down the math problem (numerical equation), you can solve the problem using any subtraction method of your choice, preferably the column method. Always remember to include the unit of measurement in the final answer.
Step 5: VERIFY YOUR ANSWER:
Finally, check your work to make sure that your answer is correct. For instance, estimate the answer and see if it is close to what you expected. However, if the answer is not what you expected, go back to step one and start all over again.
Examples on how to subtract two-digit numbers up to five digits word problems
Example One
Step 1:First, the important numbers here are 9,990,941 and 9,151,964. The keyword(s) found in the word problem is "how many more."
Step 2: Next, ask yourself, "How can I solve this problem?" As seen in step 1 above, the keyword found in the word problem calls for a subtraction operation.
Step 3: Construct short phrases to represent the given word problem and write down a numerical equation representing the information in the word problem.
- Number of volumes the University of Michigan Library holds = 9,990,941.
- Number of volumes the University of California-Los Angeles library holds = 9,151,964.
- Therefore, the number of more volumes the University of Michigan Library holds compared to the University of California-Los Angeles library = Number of volumes the University of Michigan Library holds - Number of volumes the University of California-Los Angeles library hold.
9,990,941 - 9,151,964 = ?
Step 4: Last but not least, from step 3 above, stack the values in the equation you formed so that their place values should line up. Then, go ahead and add the values. Also, do not forget to add the unit of measurement to the final answer.
So, the University of Michigan Library holds 838,977 more volumes than the University of California-Los Angeles library.
Step 5:Finally, check your work to ensure your answer is correct. For example, estimate the answer and see if it is close to what you expected. However, if the answer is not what you expected, go back to step one and start all over again.
Example Two
Step 1:Here, the important numbers are $9,765,846 and $7,459,213. The keyword(s) found in the word problem is "how much more."
Next, ask yourself, "How can I solve this problem?"
Step 2: From the situation that the problem is describing and the keyword found in the word problem calls for you to perform a subtraction operation.
Step 3:Construct short phrases to represent the given word problem and write down a numerical equation that represents the information in the word problem.
- Amount of money they have raised so far = $7,459,213.
- Total amount of money they need to raise = $9,765,846.
- Therefore, the amount of money they need to raise now = the amount they need to raise – the amount they have raised so far.
$9,765,846 - $7,459,213 = ?
Step 4:From step 3 above, stack the values in the equation you formed so that their place values should line up. Then, go ahead and add the values. Also, do not forget the unit of measurement if any.
So, they need to raise $2,306,633 now.
Step 5:inally, check your work to ensure your answer is correct. For example, estimate the answer and see if it is close to what you expected. However, if the answer is not what you expected, go back to step one and start all over again.
