The image is a page from a math worksheet titled "Problemes de la segunda 3". The page is divided into two sections. 

The top section is titled "Calcular el segundo determinant" which translates to "Calculation of the determinant". Below the title, there is a table with three columns and three rows. The first column is labeled "1.1.2" and the second column is numbered "2.3". The table has three columns, each with a different mathematical equation written on it.

In the first column, there are three equations written in black ink. The equations are:

1.4.5.6.7.8.9.10.11.12.13.14.15.16.17.18.19.20.21.22.23.24.25.26.27.28.29.30.31.32.33.34.35.36.37.38.39.40.41.42.43.44.45.46.47.48.50.51.52.53.54.55.56.57.58.59.60.61.62.63.64.65.66.67.68.69.70.71.72.73.74.75.76.77.78.79.80.81.82.83.84.85.86.87.88.89.90.91.92.93.94.95.96.97.98.99.99."

At the bottom of the page, there appears to be a list of problems written in Spanish. The problems are written in a neat and organized manner, with each problem having its own set of numbers and equations.
