Explicación

La suma correcta es 42 (23 + 19). 41, 44 y 40 no combinan las cifras correctamente.

105+37=142. 132, 148 y 139 no suman esos valores.

56+77 sería 133, pero 58+77 es 135.

260+39 sería 299, calcula 240+59 = 299.

6 + 489 = 495. 495 aparece también como opción correcta en otros contextos, pero aquí es correcto.

312+88=400. Las otras sumas dan 390, 408 o 392.

150+150=300. Las otras sumas no coinciden.

7+68=75. 73, 77 y 78 no coinciden.

999+1 = 1000. Las demás opciones no reflejan el incremento correcto.

265+35=300. 295, 320 y 280 son fallos comunes.
