Realizar los siguientes ejercicios en una hoja de la carpeta: 1. 12 + (-67) = 2. (- 32)+ 67 +( 23) = 3. (- 5) + 72 + (- 54 ) = 4. 68 + 39 + (- 56) = 5. 12 + ( - 12) + 64 + ( - 63) = 6. 1252 + ( - 253 ) + 306 + (- 908) = 7. un submarino llega a una profundidad de 3225 m bajo el nivel del mar. luego necesita estar a 1550 m bajo el nivel del mar. ¿cuánto debe subir o bajar? 8. la temperatura al escalar un nevado disminuye 1° cada 250 m. en una emergencia, el guía baja a un par de escaladores desde los 5200 m sobre el nivel del mar hasta los 1200 m. ¿cuántos grados ganaron o perdieron los escaladores?
