Question

which three cards have equal values? 4 × 32 3 × 42 4 × (30 + 20) 3 × (40 + 2) (3 × 40) + (3 × 2) (4 × 3) + (4 × 2)

Explanation:

Step1: Calculate value of 4×32

$4\times32 = 128$

Step2: Calculate value of 3×42

$3\times42=126$

Step3: Calculate value of 4×(30 + 20)

$4\times(30 + 20)=4\times50 = 200$

Step4: Calculate value of 3×(40 + 2)

$3\times(40 + 2)=3\times40+3\times2=120 + 6=126$

Step5: Calculate value of (3×40)+(3×2)

$(3\times40)+(3\times2)=120+6 = 126$

Step6: Calculate value of (4×3)+(4×2)

$(4\times3)+(4\times2)=12 + 8=20$

Answer:

$3\times42$, $3\times(40 + 2)$, $(3\times40)+(3\times2)$
