Since carter multiplies by 10 and then by 2 and adds the two, here we have been given 16 * 12
Step 1: Carter would first multiply the number by 10. This would be = 16*10
Step 2: Carter would multiply the number by 2. This would be = 16*2
Step 3: He would add the two. This would be = (16*10) + (16*2)
Carter's solution would be:
=16*12
=(16*10) + (16*2)
= 160 + 32
= 192
