●【病例呈现】●请把下面整万的数改写成用“万”作单位的数:●【病因诊断】●东东做得不正确。东东混淆了“改写”与“求近似数”的概念。“改写”不改变数的大小,改写过程应该用“=”作为连接符号。求近似数时才用“≈”连接。
● 【Case Presentation】 ● Please rewrite the following number into the number of units: “Etiology Diagnosis” ● Eastern do not correct. Dongdong confused “rewrite ” and “seek approximation ” concept. “Rewrite ” does not change the size of the number, rewrite process should use “= ” as the connection symbol. Find the approximate number with “≈ ” connection.
