Practice problem
Which of the following are equivalent to the above expression?
1×(3+2+6+4+4+5)1\times (3+2+6+4+4+5)1×(3+2+6+4+4+5)
1×3+2×6+4×4+51\times 3 + 2\times 6 +4 \times 4 + 51×3+2×6+4×4+5
1+(3+2)+(6+4)+(4+5)1+(3+2)+(6+4)+(4+5)1+(3+2)+(6+4)+(4+5)
(3+2)+(6+4)+(4+1)+5(3+2)+(6+4)+(4+1)+5(3+2)+(6+4)+(4+1)+5
(3+2+6+4)+(4+1+5)(3+2+6+4)+(4+1+5)(3+2+6+4)+(4+1+5)
Type a concept, like “slope” or “photosynthesis”.
