How to multiply 2 by multiples of 5 using mental math
The Core Strategy: Break Apart and Double
When multiplying by 2, you are essentially doubling the number. We use the Distributive Property to break the factor into its place values (or components) and double each one separately before adding them back together.
 
Example: 2×65
Step 1: Break the Factor into Simple Parts
Split 65 into the parts you can double easily. Since 65 is 60+5, you split it into its whole ten and its ones digit.
2×(60+5)
 
Step 2: Double Each Part
Now, double each part separately:
Double the Tens: 2×60
(Remember, 2×6=12)
2×60=120
Double the Ones: 2×5
2×5=10
 
Step 3: Add the Results
Finally, add the two doubled results together:
120+10=130
So, 2×65=130.
