Question

Temperatures 26${}^{\circ }$C above 0${}^{\circ }$C and 13${}^{\circ }$C below 0${}^{\circ }$C can be represented as

• A. -26${}^{\circ }$C and +13${}^{\circ }$C
• B. +26${}^{\circ }$C and -13${}^{\circ }$C
• C. -26${}^{\circ }$C and -13${}^{\circ }$C
• D. +26${}^{\circ }$C and +13${}^{\circ }$C

Answer 1

The correct option is B

+26${}^{\circ }$C and -13${}^{\circ }$C

Considering 0${}^{\circ }$C as 0 of the number line, we can represent 26${}^{\circ }$C above 0${}^{\circ }$C as +26${}^{\circ }$C, while 13${}^{\circ }$C below 0${}^{\circ }$C as -13${}^{\circ }$C.
