A. Data in the column has an error

B. Column data formatting error

C. Calculation result error

D. The column width is insufficient to display the numeric value

D — Widening the column resolves '###' display issues.

4
New cards

In Microsoft Excel, what does the '#VALUE!' error in a cell indicate?

A. Column width is insufficient

B. Data used in the formula has an incorrect data type (e.g. adding text to number)

C. No result

D. Function name typed wrong

B — #VALUE! occurs when a mathematical formula receives a text string or mismatched type.

5
New cards

B. Ctrl + Shift + Page Up

C. Shift + Home

D. Ctrl + Home

D — Ctrl + Home navigates directly to cell A1.

7
New cards

In Microsoft Excel, cell A1 contains 'Nguyễn Lan' and B1 contains 'Anh'. Entering '= A1 +B1' in C1 yields:

A. Nguyễn Lan Anh

B. Nguyễn LanAnh

C. #VALUE!

D. No result

C — The '+' operator is for numeric addition. Text concatenation requires '&' or CONCAT.

Nếu bạn muốn kết quả trả về là chuỗi văn bản (như phương án A hoặc B), bạn phải dùng các cách sau:

  • Dùng toán tử &: =A1 & " " & B1 (cho ra kết quả Nguyễn Lan Anh) hoặc =A1 & B1 (cho ra kết quả Nguyễn LanAnh).

  • Dùng hàm CONCAT hoặc CONCATENATE: =CONCAT(A1, " ", B1).


8
New cards

In Microsoft Excel, cell A1 contains 9.78 (right-aligned numeric format). Entering '= INT(A1)' in B1 yields:

A. 9.5

B. #VALUE!

C. 10

D. 9

D — INT rounds down to the nearest integer (9.78 -> 9).

9
New cards

In Microsoft Excel, cell A1 contains '9,78' (left-aligned text format). Entering '= INT(A1)' in B1 yields:

A. 9.5

B. #VALUE!

C. 10

D. 9

B — INT on a text string formatted with invalid comma delimiter returns #VALUE!.

  • INT(number) nhận một giá trị số và làm tròn xuống đến số nguyên gần nhất.

  • 9.78 được lưu dưới dạng số → =INT(A1) trả về 9.

  • '9,78' được lưu dưới dạng text → Excel có thể không xử lý được bằng INT() và trả về #VALUE!

*GHI NHỚ TRONG EXCEL

+) Text (văn bản) → mặc định căn trái (left-aligned).

+) Number (số) → mặc định căn phải (right-aligned).

 In Microsoft Excel, before executing the Subtotals command:

A. Data does not need sorting

B. Copy data to another area without sorting

C. Data MUST be sorted by the group key field first (Sort)

D. Filter data to another area

C — Subtotals requires pre-sorting data by the grouping column to calculate group subtotals accurately.

Subtotal (tổng phụ) là chức năng trong Excel dùng để tính toán theo từng nhóm dữ liệu, chẳng hạn tính tổng doanh thu của từng thành phố hoặc tính trung bình điểm của từng lớp.

Ví dụ, bảng dữ liệu ban đầu:

Thành phố

Doanh thu

Hà Nội

100

TP.HCM

200

Hà Nội

150

Cell A1102 contains 'BM00900F'. Entering '= VALUE(MID(A1102, 3, 5))' and '= MID(A1102,3, 5)' in B1102 and C1102 yields:

A. 900 and '00900'

B. '00900' and '00900'

C. 0900 and 900

A — MID extracts string '00900'; VALUE converts string '00900' into number 900.'

Ô B1102: =VALUE(MID(A1102,3,5))

  • MID(A1102,3,5): Lấy 5 ký tự, bắt đầu từ ký tự thứ 3 → "00900".
