Worked solution

1. 利用乘法分配律对原算式进行合理展开变形

43×102=43×(100+2)=43×100+43×243 \times 102 = 43 \times (100 + 2) = 43 \times 100 + 43 \times 2

2. 对比题干等式并作出正误判断

题干中给出的等式右边为 43×100+243 \times 100 + 2。
由于 43×2=86≠243 \times 2 = 86 \neq 2,显然有 43×100+43×2≠43×100+243 \times 100 + 43 \times 2 \neq 43 \times 100 + 2。
因此该说法是错误的。
