Lewis tried to evaluate 4\times3{,}4824×3,4824, times, 3, comma, 482 step by step. \phantom{=}\greenD{4}\times\blueD{3 {,}482}=4×3,482empty space, start color #1fab54, 4, end color #1fab54, times, start color #11accd, 3, comma, 482, end color #11accd
{\text{Step } 1}Step 1start text, S, t, e, p, space, end text, 1 =\greenD4 \times (\blueD{3{,}000} + \blueD{400} + \blueD{80}+\blueD2)=4×(3,000+400+80 +2)equals, start color #1fab54, 4, end color #1fab54, times, left parenthesis, start color #11accd, 3, comma, 000, end color #11accd, plus, start color #11accd, 400, end color #11accd, plus, start color #11accd, 80, end color #11accd, plus, start color #11accd, 2, end color #11accd, right parenthesis
{\text{Step } 2}Step 2start text, S, t, e, p, space, end text, 2 =(\greenD4 +\blueD{3{,}000}) +(\greenD4 +\blueD{400}) + (\greenD4 +\blueD{80}) + (\greenD4 +\blueD{2})=(4+3,000)+(4+400)+(4+80 )+(4+2)equals, left parenthesis, start color #1fab54, 4, end color #1fab54, plus, start color #11accd, 3, comma, 000, end color #11accd, right parenthesis, plus, left parenthesis, start color #1fab54, 4, end color #1fab54, plus, start color #11accd, 400, end color #11accd, right parenthesis, plus, left parenthesis, start color #1fab54, 4, end color #1fab54, plus, start color #11accd, 80, end color #11accd, right parenthesis, plus, left parenthesis, start color #1fab54, 4, end color #1fab54, plus, start color #11accd, 2, end color #11accd, right parenthesis
