43+8 equals 51, and so does 41 plus a different number. To find the missing number, we need to add 2 (the difference between 43 and 41) to 8, which gives us 10. Therefore, 41+10 equals 51, the same sum as 43+8.
The student asked the question: "43+8 is the same as 41+?". This is a mathematics question that involves understanding the commutative property of addition, which states that A+B=B+ A. The question also touches on the ability to perform mental arithmetic to find the missing addend.
To solve for the missing number, we can use the fact that the order of adding numbers does not change the sum. If 43 + 8 equals 51, then 41 + 10 will also equal 51. We find this by recognizing that 41 is 2 less than 43, so we need to add 2 more to the other addend (8) to keep the sum the same, which gives us 10.
