Carlos is using the distributive property to evaluate the expression 14 (49) by using friendlier numbers. His work is shown below. Carlos’s Work

14 (49)
Step 1
14 (40 + 9)
Step 2
14 (40) + 9
Step 3
560 + 9
Step 4
569

What was the first error that Carlos made?
Step 1 should have been 14(7 + 7).
Step 2 should have been 14(40) + 14(9).
Step 3 should have been 23(40).
Step 4 should have been 5,040.
