How is making a ten to add the same as making a ten to subtract How is it different?
Making a ten to add involves regrouping numbers to create a sum that simplifies the addition process, such as turning 8 + 5 into 8 + 2 + 3 to make 10. In contrast, making a ten to subtract typically involves breaking down a larger number to find a simpler way to perform the subtraction, like adjusting 14 - 6 to 14 - 4 - 2. While both strategies aim to simplify calculations, the key difference lies in their application: addition focuses on combining numbers, while subtraction focuses on separating or reducing them.
What else can I help you with?
Why are two fractions converted into like fractions?
Because you can't add or subtract fractions that have different denominators. Making them like fractions, by multiplying so the denominators are the same, you can add and/or subtract them.
Do you add and subtract like and unlike fractions in the same way?
no, to add and subtract like and unlike fractions the denominator has to be the same,
How do you add or subtract fractions when negative?
The same as with positive ones. Make sure they have the same denominator and add or subtract their numerators.
How do you add and subtract improper fractions with different denominator?
he fact that they are improper is irrelevant. Re-scale the fractions so that they have the same denominator and thenadd or subtract as required.
Why is it important to learn how to subtract and add with different integers?
Because otherwise you would only know how to subtract and add with the same integers. Not a particularly useful skill unless just those integers turned up!

How do you add and subtract fractions with the same denominator?
it stay the same when you subtract fractions and when you add fractions.

Do you add or subtract if forces are acting on an object in the same direction?
add
How do you combine same variables with different powers?
If the numbers are being multipled or divided then you add or subtract the exponent values, respectively.
Do you subtract exponents when multiplying?
No you add them if the bases are the same.
What condition must be met before you can add or subtract fractions?
Before you can add or subtract fractions, the denominators must be the same. If the denominators are different, you need to find a common denominator by determining the least common multiple of the existing denominators. Once the denominators are equal, you can add or subtract the numerators while keeping the common denominator.
How is adding and subtracting decimals similar to and different from adding and subtracting whole numbers?
You write down the numbers you want to add and subtract, making sure the decimal points are aligned. Then, you add (or subtract) EXACTLY as you would add or subtract integers. The decimal point in the solution should be aligned with the decimal points in the original numbers.
How do you add or subtract decimals?
how do we add or subtract decimal? its the same thing as using regular subraction and addition. Example: 12.4 +8.1 ______ =20.5 The same in subtraction! Just keep the decimals alligned!
