As featured in our latest print issue, this testing mathematical puzzle requires top notch multiplication and addition skills.
Each number in the main grid can be formed by adding or multiplying a pair of numbers from the strip below. Each pair of numbers should be used twice: once as part of an addition and once as part of a multiplication. For example, a 10 and 24 in the main grid may be solved by the sums, 4 + 6 and 4 x 6, respectively. Enter each sum in the boxes below its answer. Any blanks in the strip must be deduced, with the numbers in the strip listed in ascending order.
