Fractions (Frac); Products (Prod); Pairs (Pair); Totals (Totl) - Millenium Brain Challenge Bedienungsanleitung

4.4 Fractions (FrAC)

The display shows two
fractions. Point to the one
which is greater.
In this example you would point to the fraction on the left, as
12÷ 13 is greater than 6÷ 7.

4.5 Products (Prod)

The display shows two
products (multiplications).
Point to the one which is
greater. In the example on
the right, you would point to 15x5.

4.6 Pairs (PAIr)

The display shows a number of ? signs. Imagine that each ?
sign is " covering up" a symbol (a letter, number or shape).
Touch a pair of signs to " uncover" the corresponding
symbols. If the two symbols are identical, the squares they
were occupying are cleared. If not, the squares revert to the ?
sign. The object is to clear the entire grid by matching all
the pairs.
In this activity, you are given a fresh time allowance each
time you locate a pair.

4.7 Totals (totL)

The upper lines contain several numbers and a total that
must be reached by adding some of them together. Lower
down, there is a set of double question marks to show how
many numbers must be added up. For example:
1 2
– –
1 3
1 5 x 5
10
6
–
7
4 x 1 8
