6)2.1 + 18:9<br> What is the answer and the explanation
Lapatulllka [165]
2.1+18.9

The answer is going to be 21 because 9+1=10, you then carry the 1 for 8 so it’s going to be 9+2 which equals to 11 now you carry the 1 to the 1 so it’ll be 2. Therefore it’s 21.0 or just cancel out the 0 and just leave it as 21.
