Find your number, look Right next door, five or more just add one more, four or less just ignore...

What is 61424 rounding each addend to the nearest thousand?
It is 61000.
How do estimate each sum or difference?
Sum is the result of an addition problem, while difference is the result of a subtraction problem. Addend Subtractend + Addend - Subtractor Sum Difference
What property states that multiply a number by a sum you can multiply each addend by the number and add the products?
distributuve property
What is front end rounding of decimals?
Instead of rounding each number to a given place value, we round whatever number is in the front.

What is the difference between compatible numbers and rounding?
Rounding is going to the nearest tens, hundreds, thousands etc., depending on the problem. Compatible numbers are numbers the work well with each other. Both of these are estimating.
Select all that have sums equal to 600 when each addend is rounded to the nearest hundred.?
What is the addend 600 rounded to the nearest hundred
What are the rules to Estimating products and quotients of mixed numbers?
Estimating sumsUse rounded numbers to estimate sums.Example 1Give an estimate for the sum of 19.61 and 5.07 by rounding to the nearest tenth.Round each number to the nearest tenth.Example 2Estimate the sum of 19.61 + 5.07 by rounding to the nearest whole number.Round each number to a whole number.Estimating differencesUse rounded numbers to estimate differences.Example 3Give an estimate for the difference of 12.356 - 5.281 by rounding to the nearest whole number.Round each number to the nearest whole number.Now subtract.So 12.356 - 5.281 ≈ 7.Estimating productsUse rounded numbers to estimate products.Example 4Estimate the product of 4.7 × 5.9 by rounding to the nearest whole number.Round each number to a whole number.So 4.7 × 5.9 ≈ 30.Again, in decimals, as in whole numbers, if both multipliers end in .5, or are halfway numbers, rounding one number up and one number down will give you a better estimate of the product.Example 5Estimate the product of 7.5 × 8.5 by rounding to the nearest whole number.You can also round the first number down and the second number up and get this estimate.In either case, your approximation will be closer than it would be if you rounded both numbers up, which is the standard rule.Estimating quotientsUse rounded numbers to estimate quotients.Example 6Estimate the quotient of 27.49 ÷ 3.12 by rounding to the nearest whole number.Round each number to the nearest whole number.

What combines multiplication and addition by multiplying each addend by the number and adding the products?
The distributive property of multiplication over addition.
