Sometimes, always, never?
If you multiply an even number by 5, the answer is a multiple of 10. A hexagon has no lines of symmetry. If you fold a square in half, you get two triangles. An even number divided by an even number equals an even number. Multiplying gives a higher answer than the number you started with.

If you add a 2 digit number to a 3 digit number, you get a 3 digit answer. Polygons have equal sides. An odd number multiplied by an odd number equals an odd number. Square numbers cannot be prime numbers. A fraction is smaller than a whole.

A circle has infinite lines of symmetry. All lines drawn on a circle will be lines of symmetry. A circle has no rotational symmetry. A quadrilateral has 2 lines of symmetry. Number of edges = order of rotational symmetry.

Whole numbers divided by 2 give whole number answers. Adding to a number always gives a higher value answer. The method for finding the area of a rectangle can also be used to find the area of other parallelograms. Half of any positive integer will always be greater than zero.

Any number times 0 equals 0. Any number times 1 equals 1. Any number times 10 will end in a zero. Any number times 5 will end in a zero. Any number times 0.5 will equal half of itself.

Perpendicular lines are not parallel. multiplying a 3-digit number by a 2-digit number gives you a 6-digit answer. Triangles don’t have obtuse angles. A shape with line symmetry also has rotational symmetry.

If you multiply a whole number by 10 it will end in zero. If you divide a whole number by ten it will end in zero. If you fold a square in half, you get two triangles. If you add two 3 digit numbers you will get a 4 digit answer. A circle has no lines of symmetry
