Year 4 homework

Start with what you can solve.

Rhombus minus pentagon = rhombus, therefore the pentagon must equal zero.

Then replace the pentagon in the calculation with 0.

Next step is (+ - 4 = 0), therefore the cross must equal 4.

Substitute the cross with the 4 and you can then work out the last part.

Not very well explained, but I don't have my interactive whiteboard handy! Well that's my excuse. .

is this a type of algebra ?
can't see the point of it.

Learning algebra helps to develop your critical thinking skills. That includes problem solving, logic, patterns, and reasoning. You need to know algebra for many professions, especially those in science and maths.

I'm probably a bit odd, but I enjoy puzzles like this. However, I have to admit to being a bit rusty!

well i didn't come across algebra til the first year of secondary school, and i resented it.
i felt that maths was about numbers, not letters which belonged in the other subjects, where they gathered into sentences.
i thought maths was taking over, as if literature tried to push into geometry or compound interest.
why do i suddenly think of Dickens; mr micawber ?
i came second only to Japanese girl in maths in the first year. by the time it came to O-level i got unclassified.
but 10 years later i did it externally, and got the middle grade pass. i was the only person in the hall not using a calculator, long division etc all down the side of the paper. and had to do differential calculus, and parabolas. though what they are for i couldn't say.
