Millions of calculators are thrown away every year, many with used batteries that cannot be replaced. The X MARK 1 calculator is completely solar powered, using natural, renewable energy. It contains no battery at all, so there’s no harmful waste. To reduce waste even further, recycled paper is used for the calculator packaging.
Work out your profit margins automatically using separate cost-sell-margin keys, without the need for complex formulae. It’s the easiest way to simplify complex calculations and save time. Other functions include a Grand Total memory as well as shift, percentage, sign change and square root keys. A key roll over function allows speedy entry of figures without keys blocking.
Sleek and stylish, the X MARK 1 calculator has a smart, glossy surface – available in gleaming white or brilliant black – with an elegant aluminium lower case. The slim, streamlined body has an internal angled display for easy viewing. Equally important, the calculator is durable and dependable. The key tops are double-injection moulded, so embedded signs and figures don’t wear off even with constant use. It all adds up to the ultimate in style, reliability and environmental responsibility.
