What number is 10 more than 9? Explain or show how you know
"More than" means addition. Add the number before the word "more than" (10 in this case) to the number after "more than" (9 in this case).
10 more than 9 is 9 + 10 = 19.
*If it was "10 less than 9", the expression would be 9 - 10 = -1.
Let
x---------> the number
The equation that represent this situation is
\(x=10+9\)
\(x=19\)
therefore
the answer is
The number is \(19\)
