An interesting argument: that calculating devices are now ubiquitous, and math should focus on computational problem-solving instead of drilling and memorisation. An example the author cites:
Computer languages allow students to transform ideas into action. Here is a simple rule that a math teacher might describe to her students: If the number is greater than 9, carry the 10’s place; otherwise add the number to the bottom row.
The solution for this can be expressed as a simple if/else statement:
if (number > 9) carry += number / 10; else bottom += number;
There are, as expected, plenty of opposing views in the comments, but it’s good food for thought. Also noteworthy: the comments aren’t completely stupid. Not-completely-stupid comments! On the Internet! WHAT IS THIS WORLD WE’RE LIVING IN
