Number sentences are a variety of numbers that equal an answer. Example: 4x6x1= 24
There are several addition sentences that equal 28, such as 14 + 14, 10 + 18, and 20 + 8. Other examples include 5 + 23 and 7 + 21. Essentially, any combination of two or more numbers that adds up to 28 can be considered an addition sentence equal to 28.
165 + 165 = 330

A negative number TIMES a positive number will equal a negative number. A negative number DIVIDED BY a positive number (or vice versa) will equal a negative number. With addition and subtraction, it all depends on what the numbers are.
To write a horizontal number sentence that has a sum of nine, you can use addition. For example, you could write "4 + 5 = 9" or "3 + 6 = 9." Both of these sentences show two numbers that, when added together, equal nine.
The first number (01001101) is equal to the decimal number 77. The second number (00100010) is equal to the decimal number 34. If you add the two together in decimal, you get 111. Expressed as a binary number, 111 is equal to 01101111.

I don't really know what you mean but. 27+27=54
The sum of two number times a third numberis equal to the sum of each addend times the third number
In addition, it depends on which is larger. In multiplication, a negative times a positive is alway negative.
The Addition Property of Equality states that if you add the same number to both sides of an equation the two sides remain equal. Source- My mathbook.
