The La Nina is the "cool phase" of the El Nino-Southern Oscillation (ENSO), which is a natural climate pattern that occurs in the Pacific Ocean. La Nina is caused by a build-up of cooler-than-normal waters in the tropical Pacific, the area of the Pacific Ocean between the Tropic of Cancer and the Tropic of Capricorn.
245 + (45 ÷ 3 + 5) × 6 - 125 = ?
√1764 + 35 × 8 + 39 = ?2
12% of 450 + 16% of 1500 = ?
45% of 360 - 160 + ? = √324
56 ÷ 14 × 4 – 316 + ? 2 = 100
