Tim 7: Et L'eclipse Totale is an edutainment game focusing on 4e level of Mathematics. The contents of the subject are: Master the calculation: Relative numbers and decimal relative numbers (rule of signs and parentheses); Fractions and inverse; Powers and scientific notation; Statistics (count table, frequencies, percentage of a value). Calculate with an unknown: Development (formulas, factorization); Order and operations; Equation (equate and solve); Proportionality, speed and linear application. Manipulate the figures: Projections (theorem of the midpoints of the sides of a triangle); Orthogonal and cosine projections (orthogonal projection, coordinates of the midpoint of a segment, cosine of an angle); Translations and rotations (image of a figure and a segment, tracing method); Spheres and balls (area and volume). Know how to demonstrate: Lines, circles and distances (tangent, axis of symmetry, bisector); Remarkable triangles and lines (orthocenter, median, bisector, height, bisector, center of gravity, inscribed circle); Pythagorean theorem and its converse; Right triangle. You play as Tim 7, named as such due to being kidnapped by Dr. Gaaf and being the 7th guinea pig of his experiments. Tim 7 has lost his memories and you need to help him escape the island. Less
