∙ 10y agoIs the question suppose to be "a compatible number"? If it is then it's a number that is close to a number in a math problem. So it makes it easier to estimate if you have to use mental math. For example : to solve 40/4.7 --> you round 4.7 to 5 --> then divide 40/5 = 8
compatible numbers mean , for example, 56 x 8. if you wanna find compatible numbers to make the problem easier, then see what 56 is close to. its close to 70, so 70 x 8 would be 560.
A compatible number is a number that is easy to add when you add it together.

The answer depends on the context. If considering the 1877 + 11 then a compatible number would be 1880 but if considering 1877 + 11,000,000,000,000,000 the compatible number is 0.

Compatible number is one that is near the actual number, but is easier to use for addition, subtraction, multiplication, or division. In other words, it is easy to use for estimating the answer to an arithmetic problem. Example: 38 + 23 A compatible number for 38 might be 40 A compatible number for 23 might be 20 (or 25) The sum of the compatible numbers would be 60 (or 65). So you know the answer will be near there. If you choose 40 and 20, you know that one of your compatible numbers is a little too high, and the other is a little too low. So your estimate of the answer (40+20=60) will be pretty close. (Your estimators are high by 2 and low by 3, so you know your answer is low by 1. It is really 61, not 60.) If you choose 40 and 25, you know that both of your compatible numbers are a little too high, so your answer will be a little more high. As it turns out, both "estimates" are high by 2, so the estimated answer (65) is high by 2+2=4. The actual result is 61 = 65-4
a square number is a multiplicatin problem that is the same for an example 6x6=36 because it makes a square a prime number is basicly a problem that has no multiplicatin problem except a 1 for an exsample 11x1=11
